chemistry of bubbles

Soap Bubble Chemistry Theresa Colby Montessori Elem School Al Oldenburg Lindblom HS Al Tobecksen Fenger HS Objectives: 1.Students will understand the chemistry of soap bubble films. Soap bubble containing sucrose, sodium alkyl ether sulfate (AES)-detergent and poly(vinyl alcohol) (PVA) (or partially hydrolyzed poly(vinyl alcohol) (PVAAc)) often maintains a spherical shape on various solid surfaces, including concrete, asphalt, tile, and grass after landing. —zwitterionic surfactant: This type of surfactant is often used in mild detergents for sensitive skin. A thin layer of water lies between the two layers of soap molecules, sort of like a water sandwich with soap molecules for bread. In terms of physics, the mechanism of stabilizing a soap film is the well-known “Marangoni effect” [4]. A recipe for making a soap that will produce soap bubbles that can last for many months in a jar or other closed environment. This study was supported in part by Japan Science and Technology Agency (JST) “Promotion of Pre-University Research Activities in Science”. 1 was stable on both grass and a wooden deck (Figure 21). Other examples of the Marangoni effect include the ‘tears’ observed in wine, the spontaneous motion of a camphor particle on water, and the spontaneous motion of the Belousov-Zhabotinsky reaction. However, such a bubble will typically rupture upon impact with the ground (landing). Soap bubble No. Take a look at the science behind bubbles. Glycerin forms weak hydrogen bonds with water, delaying evaporation. This recipe requires handling some hazardous material. By this simplified method, the surface tension of deionized water was 67.9 mN/m, whereas the exact surface tension of water at 20 °C is 72.8 mN/m [17]. 1 can yield a solid residue. Eventually, No. Plateau experimented with soap films to solve the problem. Poly(vinyl alcohol) (PVA) is commonly used in soap bubbles. Each soap … Daughter Bubble Cascades Produced by Folding of Ruptured Thin Films. Practical Chemistry of Long-Lasting Bubbles. Bubble and Foam Chemistry - by Robert J. Pugh September 2016. If bubbles that are different sizes meet, then the smaller bubble will bulge into the large bubble. These bubbles happen because of carbonation. If two differently sized soap bubbles are connected together, the smaller bubble becomes smaller and larger bubble becomes larger. The refractive indexes of the air and detergent are 1.0 and 1.4, respectively. Momoko Ueno, Naho Isokawa, Kazuki Fueda, Suzuka Nakahara, Hinako Teshima, Nanami Yamamoto, Haruka Yokoyama, Yukina Noritsugu, Koushi Shibata, Kourin Miyagawa, Seiko Tanaka, Takashi Hirano, Ayako Fujito, Ayaka Takashima, Kenichi Kanno. Sulfate and carboxylate groups are the typical anionic groups. Photographs of the obtained soap bubbles are presented in Figure 20. If the bubbles do not explode, wait a little longer for the gas mixture to displace air from the tubing. There are a couple times when bubbles aren’t round. A mathematical problem known as “Plateau’s problem,” which indicates the existence of an area with the minimal surface for a … For example, the viscosity of an aqueous solution of 100% deacetylated PVA (fully hydrolyzed PVA) gradually increases over time, although PVAAc, in contrast, does not [5]. It was proposed that bubble flight with a long air time resulted in the external desiccation of the bubble, leading to the formation of an external resin film. Students view both cups at the same angle, and can see the coin at the bottom of the cup with the detergent, but not in the cup without detergent. A disposable measuring pipette was used for droplet counting; this device is quite inexpensive and the samples are too viscous for a capillary-type stalagmometer to be used. No matter what shape a bubble has initially, it will try to become a sphere. Students hypothesize that the low surface tension of the long-lasting bubble is not the sole reason for its long lifetime on various solid surface. Glycerol or sucrose was then dissolved in the polymer solution. For example, the surface tension of water at 20 °C is 72.8 mN/m [19], whereas that of soap bubble No. Each soap molecule is oriented so that its polar (hydrophilic) head faces the water, while its hydrophobic hydrocarbon tail extends away from the water layer. 3 was the low-molecular-weight component, i.e., sucrose or glycerol; however, No. Surface Tension - Definition and Experiments, How to Perform the Pepper and Water Science Magic Trick, How Superheating Works - Water in a Microwave, Ph.D., Biomedical Sciences, University of Tennessee at Knoxville, B.A., Physics and Mathematics, Hastings College. When two bubbles meet, they will merge walls to minimize their surface area. A desiccator with a silica-gel desiccant provides a low humidity environment, whereas higher humidity can be obtained without the silica gel. Where M is the weight of one droplet, g is the gravitational acceleration, and 2πr is the circumference (r: radius) of the measuring pipette. Through designing long-lasting soap bubbles and discussing the reasons behind their longevity, students can experience basic material chemistry. However, this simplified method is sufficient for comparing the surface tensions of various soap bubble solutions in this laboratory experiment. Learn about surface tension 4. The dropping speed was adjusted to approximately 1 droplet every 10 s, by varying the angle of the three-way stopcock. PVA is synthesized by the deacetylation of PVAc. The bottom of the measuring pipette was filed flat and the collection bottle was weighed before the experiment. At 40% RH, soap film No. It is believed that the hydrophobicity of the acetyl groups in PVAAc inhibits the crystallization of PVA. Learn that all liquids form bubbles … PVA forms isolated coils at low concentrations and entangled chains at high concentrations (Figure 6) [6]. But the way bubbles are formed is actually a bit more complicated than that. —The number of unbreakable bubbles is calculated as an average of five replicate experiments. To determine the relationship between the relative humidity (RH) and lifetimes of the soap bubbles, the longevities of soap films were measured at four RH levels. A chemistry laboratory is required. The polymer increases the mechanical strength of the soap film by the viscoelastic behavior of the polymer solution. The stability, size, and color of soap bubbles depend upon chemistry and physics. It was suggested that flight in the air for over 15 s resulted in desiccation of the soap bubble, leading to the formation of an external resin film. Dr. Helmenstine holds a Ph.D. in biomedical sciences and is a science writer, educator, and consultant. [20] Moreover, the PVA forms a physically cross-linked gel from an aqueous solution, as reported for the “cast-drying method” [21] or “freezing/thawing technique” [22]. Using special bubble solution, a large thin film of solution is made in the loop. Douglas, J. Bubble oscillation is characterized as the expansion and contraction of the bubble tail near the gas microcavity. The best place for the long-lasting bubble experiment is outdoors, because low humidity, high temperature, and breezy conditions are preferable for the desiccation of the soap bubbles. Their brilliant colors, their simple form and their extraordinary delicateness, have not only been a delight to children, but have been of interest to everyone including The Chemistry (and a little Physics) of Soap Bubbles. Helmenstine, Anne Marie, Ph.D. (2020, August 26). The surface tension was measured using the drop-weight technique, which did not require the use of a stalagmometer (Figure 15, Figure 16). How can you make bubbles last longer? When the height of the wire is increased by spreading, the side surface area is increased and the soap film forms on the vertical surface of the wire (Figure 14B). Liquid Soap (Dawn): Dawn dish soap has multiple ingredients. Equation 2 gives the condition for interference, as shown in Figure 11. where t is the film thickness–optical pass difference, θ is the angle of refraction related to the viewing angle, λ is the wavelength of the incident light ray, and n is the refractive index. PVAAc (50 g) was swelled in deionized water (500 mL) in a 1 L Erlenmeyer flask overnight. The lifetime of the soap film in the desiccator tended to be shorter than that in the dry glove box, because the humidity gradually decreases in the desiccator. At that time, PVA soap bubble also gave unbreakable bubble (Table 4). Ann. Soap molecules consist of chains of atoms of carbon and hydrogen. Bubbles are beautiful, fun, and fascinating, but do you know what they are and how they work? The following detergents were also examined for long-lasting bubbles: JOY (P & G, JAN: 4902430560801), CHARMY Magicka (LION, JAN: 4903301189848), and Cucut Clear Sterilization (KAO, JAN: 4901301288561). Miller, R.; Joos, P; Fainerman, V. B. If the concentration is high enough, it will form a micelle. Soap film is made from soap and water (or other liquid). Glycerin often is added as an ingredient. On the other hand, sucrose does not prevent the formation of the resin film outside the bubble, because sucrose is a solid at room temperature. As you continue heating the water, the molecules gain enough energy to transition from the liquid phase to the gaseous phase. The Science of Bubbles: All you need to make a bubble is soap, water, and air…sounds pretty simple right? The air must blow fast enough to make bubbles. Although CO 2 is most common for beverages, nitrogen gas is sometimes deliberately added to certain beers. The film also did not rupture after pricking to form a hole (Figure 24). Parkinson, L.; Sedev, R.; Fornasiero, D.; Ralston, J. A bubble is a thin film of soapy water. Phys. Equation 2 shows that the bubble colors (i.e., the wavelength of the refracted light) depend on both the viewing angle and the film thickness. DuPont Specialty Chemicals Technical Information, “QUILON Chrome Complex for Improved Performance of Polyvinyl Alcohol Paper Coatings, Films, and Adhesives” (http://zaclon.com/pdf/elvanol_quilon_paper.pdf), 25 July 2015 access; Miyoshi, R.; Nakanishi, T.. Bercea, M.; Morariu, S.; Rusu, D. In-situ Gelation of Aqueous Solutions of Entangled Poly(vinyl alcohol). Is there anything that can be done to accelerate the popping of these bubbles? chemistry, bubbles, surface tension, evaporation . Hydrogen or methaneis used to blow bubbles which float in air and which can be ignited. Finally, the chosen detergent was mixed into the solution carefully to prevent foaming. https://www.thoughtco.com/bubble-science-603925 (accessed February 23, 2021). Helmenstine, Anne Marie, Ph.D. "What's the Science Behind Bubbles?" 1 and No. Sun, J.; Bhushan B.; Tonga, J. These bubbles disappear over time, but it can take minutes or sometimes hours (eg. Bubbles eventually burst once the layer of water evaporates, but adding glycerin lengthens the life span of bubbles. Toronto-based Spin Master Toys' Catch-A-Bubble takes bubble strengthening … Marangoni, C. G. M. Ueber die Ausbreitung der Tropfen einer Flüssigkeit auf der Oberfläche einer anderen. Unbreakable soap bubbles should be tough, because they land on solid surfaces. The air must blow fast enough to make bubbles. Structure and Morphology of Freeze/Thawed PVA Hydrogels. It was released in 1966 and it is one of those songs that after you heard it, you just can’t get it out of your head. Most of the bubbles that you see are filled with air, but you can make a bubble using other gasses, such as carbon dioxide. It is well known that the color of a soap bubble changes during flight, which is due to desiccation and the reduction in the film thickness [7, 8, 9]. Hassan, C. M.; Peppas, N. A. Because the humidity inside the glove box gradually decreases, this experiment requires 2 days. What's the Science Behind Bubbles? To prepare a film from solution No. Then the loop is then pulled through the air to form a giant bubble! Liquid foams are sometimes made relatively long-lasting—e.g., for fire … The humidity inside the glove box can be decreased with calcium chloride. Close this message to accept cookies or find out how to manage your cookie settings. The objective of this experiment is to introduce students to material chemistry through a familiar plaything. Format), Citation-(EndNote HPC is used as a food additive. Grosse, A. V. Soap Bubbles: Two Years Old and Sixty Centimeters in Diameter. The bubble was then punctured with a sharp pencil, whereupon it was seen that the ruptured bubble consisted of two phases (Figure 26): an internal soap bubble and an external resin film. Format). Desiccation of the solvent decreases the solubility of the polymer, at which point phase separation can take place. In addition, if you maintain the fabric moist, the pores will not clog, and you’ll blow much better bubbles. Although the surface tension may be affected by the viscosity of the soap-bubble solution, all of the bubble types, which had varying solutions, exhibited similar surface tensions. 1 and 3 exhibited different behaviors, although the difference between these two bubble types was only the low-molecular-weight component, i.e., sucrose or glycerol, as previously stated. After 24 h, the number of remaining films was counted. 1, which is often stable on a solid surface, e.g. ThoughtCo, Aug. 26, 2020, thoughtco.com/bubble-science-603925. 1871, 143, 337-354. Students concluded that the soap bubble consists of PVA (PVAAc), AES-detergent and sucrose gives long lasting spherical bubble stable on various solid surface. The soap film tends to form figures of minimum surface area. Tokyo, Japan - Researchers from Tokyo Metropolitan University studied the dynamics of foams. The film that makes the bubble has three layers. for 20% SDS). 4 often appeared to consist of a lower hemisphere only, because cloudiness accumulated in that region. A bubble is just air wrapped in soap film. Test to see whether you get bigger bubbles! 1, a plastic cup (diameter, 56 mm; height, 68 mm) was dipped into soap solution No.1 in a laboratory dish (Figure 17). To examine its structure, No. The Chemistry of Bigger Bubbles Yvonne Tuck Ericson Academy 3600 West 5th Avenue Chicago IL 60624 312-535-6660 Objectives: 1. A soap bubble can be used as an effective teaching aid to explain various interesting scientific problems to high-school chemistry students. The RH was adjusted by storing the drying agents calcium chloride and silica gel inside the glove box. Glycerin, C3H5(OH)3, extends the life of a bubble by forming weaker hydrogen bonds with water, slowing down its evaporation. Normally, the evaporation of the water in a bubble decreases the film thickness and leads to rupture. —HPC solution: HPC (50 g) was swelled in deionized water (500 mL) in a 1 L Erlenmeyer flask. For easier downloading, this book is broken into four parts: These files are in PDF format and require Adobe Acrobat Reader The instructor can choose from among a few kinds of detergents that are based on different main surfactants at the stores. Harkins, W. D.; Brown, F. E. The Determination of Surface Tension (Free Surface Energy), and the Weight of Falling Drops: The Surface Tension of Water And Benzene by the Capillary Height Method. As a physics problem, blowing bubbles is a question of how a liquid film—typically soapy water—interacts with an imposed flow of an external fluid, which is air in the case of bubble blowing. Compare the size of bubbles 2. A surfactant molecule consists of a hydrophilic head and hydrophobic tail. Find more similar words at wordhippo.com! Dynamic Surface and Interfacial Tensions of Surfactant and Polymer Solutions. "Practical Chemistry of Long-Lasting Bubbles.". Kuehner, A. L., "Long-Lived Soap Bubbles", Journal of Chemical Education, 35, 337 (July 1958). A thin layer of water is sandwiched between two layers of soap molecules. This is of interest because a surfactant can be used to decrease the surface tension of a hydrophobic bubble in order to stabilize it in air. Sarma, T. K.; Chattopadhyay, A. —Transfer the polymer solution (10 mL) into a 50 mL glass bottle with a 10 mL pipette. —Student B counts the number of bubbles produced in one blowing. To form a stable No. Students learned that the features of the soap bubbles drastically change depending on their chemical composition. 1 in Table 3 (hereafter referred to as simply “No. 1 bubble on a solid surface, over 15-s flight time is required before contact with the ground. If the instructor uses a desiccator instead of a glove box, the experiment can be completed in 1 day. When we open the bottle, we relieve the pressure and the CO 2 will come out of solution in the form of tiny bubbles. Mixtures of carbon dioxide and hydrogen are used to blow bubbles which initially sink but eventually float in air. Ueno, Momoko, Naho Isokawa, Kazuki Fueda, Suzuka Nakahara, Hinako Teshima, Nanami Yamamoto, Haruka Yokoyama, Yukina Noritsugu, Koushi Shibata, Kourin Miyagawa, Seiko Tanaka, Takashi Hirano, Ayako Fujito, Ayaka Takashima, and Kenichi Kanno. —Check the ingredient information on the detergent bottle label to determine the name of the first surfactant listed. Thus, the evaporation of No. The only difference between No. As shown in Figure 14, there are two possible saddle-shaped film surfaces. Commercially available detergents often include antifoaming agents, e.g., silicone, fatty acid salts, and polyethers, to control the amount of foam; these components may not be preferable when trying to blow long-lasting bubbles. From the results of the surface tension experiments, the students hypothesized that the low surface tension of film No. The structures of the polymers used in this experiment are shown in Figure 5. The ingredients used in this experiment was summarized in Table 1.

The soap-bubble solution was pumped into the Measuring pipette via suction by a syringe, the stopcock was closed, and the syringe was removed. —Student C counts the unbreakable bubbles from one blowing and records the data. Degree of unbreakable on ground at representative two conditions were summarized in Table 4. The number of drops from 1 mL of the soap-bubble solution was counted and collected, and the average mass per droplet was calculated for each solution. The mixture was heated in a hot water bath at 80 °C and often stirred with a stirring rod to afford the PVAAc solution. This pairing creates a pocket of air … So far as this additional experiment, we counted the bubble kept spherical shape on the ground more than 10 seconds as an unbreakable bubble. Even if No. The outside and inside surfaces of a bubble consist of soap molecules. 3 was ruptured by landing. 1 became more stable than when freshly prepared. Furthermore, if the surface is washed, it becomes increasingly slippery until the soap has been completely washed away. —Add the detergent carefully into the mixture to avoid forming bubbles. Retrieved from https://www.thoughtco.com/bubble-science-603925. If the laboratory is dry, the humidity of the room should be kept high by using a humidifier for the experiment at high humidity. Top Chemistry of Soap Bubbles Secrets. A plasticizer is an additive that increases the plasticity or fluidity of a material and it is important for toughening materials. Pepling, R. Soap Bubbles. Factors including the size and position of the gas-squirting nozzle also matter. The Terminal Rise Velocity of 10–100 µm Diameter Bubbles in Water. 2 yielded a giant bubble, while No. The chain itself is non polar... Background Research. Structural Coloration in Nature. Surface tension is an important parameter that affects the stability of a soap bubble in air, because the pressure difference between the interior and exterior of the bubble depends on both the surface tension and the bubble radius. As a teaching material, soap bubbles are used because students show interest in the science of toys.

Discover surprising insights and little-known facts about politics, literature, science, and the marvels of the natural world. Afanasyev, Y. D.; Andrews, G. T.; Deacon, C. G. Measuring Soap Bubble Thickness with Color Matching. She has taught science courses at the high school, college, and graduate levels. Salt Effects on Formation of Microcrystallites in Poly(vinyl alcohol) Gels Prepared by Cast-Drying Method. Dry ice is used as a source of carbon dioxide gas with which to blow bubbles which sink in air. 1 was often long lasting on a solid surface, with its stability depending on the ambient conditions, i.e., the temperature, humidity, wind, etc. When you dip a loop of wire into a soap solution, the surface of the film that forms represents the minimum mathematically possible area for the loop. 3 is evaporated, this bubble still retains its liquid state, because glycerol is liquid at room temperature. You see, a bubble is a layer of water that is being sandwiched together by two layers of soap. Phase Separation Processes in Polymer Solutions in Relation to Membrane Formation. Phase separation of polymer yields two phases: a high concentration and a low concentration polymer solution. A group of 3 students is ideal for this experiment. This is a book in progress. High-school students exhibited the results of this study at the science event, “Sekaiichi Ikitai Kagakuhiroba,” at Iizuka (“The Most Useful Science Plaza in the World,” Iizuka) in 2013 and 2015. The instructor can effectively show students a minimal surface with a given boundary by a demonstration with a wire (Figure 14). The Chemistry of Soap Bubbles Main Chemicals, Compounds, Components. Here, the term ‘toughening’ is not the same as ‘hardening.’ Often, hard materials are fragile (brittle) against impact. Hydroxypropyl cellulose (HPC) is water soluble cellulose derivative. 6 shown in Table 1 was a long-lasting hemispherical bubble when grounded on an indoor desk; however, this bubble type was quite vulnerable to wind. This film then behaves as a protective shell for an internal soap bubble. Bubble-type No. Jul 25, 2013 - Explore Beth Ann Hay PHOTOGRAPHY's photos on Flickr. The proposed mechanism underlying the formation of long-lasting bubbles through phase separation is supported by the fact that Nos. Solution of the Problem of Plateau. 3 bubbles by forming hydrogen bonds that prevent resin film formation outside of the bubble. Foam, in physical chemistry, a colloidal system (i.e., a dispersion of particles in a continuous medium) in which the particles are gas bubbles and the medium is a liquid.The term also is applied to material in a lightweight cellular spongy or rigid form. Physics and chemistry. When the side surface is smaller than the vertical surface, the soap film forms on the side surface (Figure 14A). PVA, sodium sulfate, and PVAAc are neither hazardous nor classified as dangerous. Soap-bubble solutions composed of various kinds of polymers and detergents were prepared and compared. Compare shapes and colors of bubbles 3. At least, it is possible that desiccation of the bubble solution, i.e., the concentration of the polymer solution, results in the phase separation of the soap bubble to give a highly concentrated polymer solution (polymer film) and low-concentration polymer solution (soap bubble) (Figure 27.B-2). Appearance. Komiya, S.; Otsuka, E.; Hirashima, Y.; Suzuki, A. Surfactants occur in four structural types (Figure 1): —cationic surfactant: Often used for antimicrobial purposes, such as benzalkonium chloride. This change affects the viscosity and elastic behavior of the PVA solution, which also depends on the molecular weight and degree of deacetylation of the PVA [6]. When you see water at a "rolling boil," … —PVA solution: Commercially available PVA laundry starch (8% PVA aqueous solution) was used. This simplified method requires no specialized equipment and the procedure is easily performed. Format), Citation-(BibTeX Note: I am interested in methods that do not alter the chemical … Detergents are also available online; one website, as an example, is the Rakuten Global Market. From popping a bottle of champagne for a celebration to cracking open a soda while watching the Super Bowl, everyone is familiar with fizz. To investigate the students’ original bubbles, the chemical structures and features of the ingredients are considered when choosing the detergent, polymer, and other chemical components. As shown in Figure 20, the soap bubbles of type No. 1 soap bubble ruptured in the following three ways: explosion in the air or on a solid surface; deflation on a solid surface over a few minutes or hours; or deflation in air followed by the descent of the resin to the ground. The mechanism behind the extended lifetime is discussed through experiments involving the surface tension and lifetimes of the bubbles under various humidity conditions. Learn that water evaporates very rapidly 5. The experiment can be carried out in one 50 minute class period. Students will build their own model for making large soap bubbles. 3 exhibited aerial flight times of over 1 min. A bubble is a thin film of soapy water. 1 either ruptured or retracted, leaving a disc-shaped resin film on the surface. If bubbles that are the same size meet, then the wall that separates them will be flat. Other individuals attempt to make the bubbles in a variety of forms. A courtyard is more amenable for counting the number of unbreakable bubbles, because it is difficult to count the bubbles as they float away in a more open space (e.g., public park). In this report, an experiment is described in which high school students investigate long-lasting bubbles of their own design. Typical functional head groups are sulfate, carboxylate, and amino groups. You can see observe this structure by making prints of bubbles or by blowing bubbles between two clear plates. The highly concentrated polymer solution can solidify to form a film after phase separation. The visible bubbles are produced by the escape from solution of the dissolved gas (which itself is not visible while dissolved in the liquid). After desiccation, soap film No. Students encounter basic chemistry through the experiment, which can be adopted into the chemistry curriculum. For example, the RI of air … During this event, over 500 people participated in soap bubble experiments, i.e., preparing the solutions and blowing soap bubbles.
