I hope you enjoy this science experiment. Does Fish Oil Dissolve Styrofoam? Add some styrofoam to acetone in a closed container. The Styrofoam does not completely disappear, even though it looks like it has. Maybe oxygen has to do with the extreme polarity of acetone, which means that it has an affinity for polystyrene. Others do it much slower. The chemical system we're considering is the polystyrene in your styrofoam. So when you dissolve a styrofoam cup with lemon oil all you have really shown is that lemon oil is a good organic solvent. Have you ever seen a foam cup appear to melt away in acetone? Some types of fish oil will dissolve Styrofoam very fast. The Styrofoam will dissolve in the acetone much like sugar dissolves in hot water. It is popular in plastics manufacturing, industrial cleaning products and some household liquids, such as nail polish remover. 0 0. Pour 20mL acetone in a container 3. Since Styrofoam is mostly air, you may be surprised by how much (or, in the end, how little) foam will dissolve in the acetone. Since Styrofoam is … Watch the Styrofoam cup slowly shrinks as it touches the acetone. Yes, acetone dissolves Styrofoam. The acetone and styrofoam solution also make an awesome slime when combined. Foam cups, bowls and containers are made of a lightweight but strong material – expanded polystyrene. b. The air in the foam leaves, and because Styrofoam consists mainly of air, when it dissolves in acetone it completely loses its structure. Always wear safety glasses, and wash your hands wel… Cookies help us deliver our Services. All you need to do is to pour a bit of acetone into a bowl, and place Styrofoam beads, packing peanuts, chunks of foam, or even a Styrofoam cup in the container. Materials for demo 039 1. After the demo is done the polystyrene will be in the bottom of the beaker. Rather, the polystyrene molecules are actually present in the acetone solution. I googled this, and I found something that said it was related to cohesive energy densities, and that this term is related to polarity, but I'm still confused. You can use a large piece of Styrofoam, Styrofoam beads or even a Styrofoam cup. It is a physical rather than a chemical reaction. The … Polarity is Why Oil and Styrofoam Interact. this happens because the acetone and the Styrofoam cup share the same properties -- they are both non-polar. Measure the time it takes for the Styrofoam to dissolve 5. Notice how much of the Styrofoam cup is left after it shrinks. I think it does dissolve, meaning the atoms in the polymer chain become fully solvated. This makes it look like you're dissolving a massive quantity of material into a small volume of liquid. Take styrofoam beads, packing peanuts, chunks of styrofoam, or even a styrofoam cup and add it to the container of acetone. The Styrofoam does not completely disappear, even though it looks like it has. Styrofoam is actually a trade name, used generically to describe polystyrene foam, a polymer made of a long chain of molecules. Claire is a writer and editor with 18 years' experience. As the air escapes the volume of the styrofoam decreases. The plastic dissolves in just about any organic solvent, not just acetone. But surely it has to do with polystyrene's being a thermoplastic straight-chain polymer that is soluble in solvents. Styrofoam dissolves in acetone in a similar way to how sugar dissolves in water. After a while. read more Acetone is a flammable, colorless liquid that is most commonly used for removing nail polish. This is because acetone is a solvent that breaks down Styrofoam. By using our Services, you agree to our use of cookies.Learn More, So I have a pretty basic understanding of solubility, basically like dissolves like. Also to know is, what happens when you mix acetone and Styrofoam? Then … From my basic understanding of electronegativity and molecule shape acetone is a polar molecule, and styrene, and I'm guessing from this polystyrene is non-polar. The reaction between Styrofoam and acetone shows how soluble this plastic is in an organic solvent and how much air is in Styrofoam. The air in the foam leaves, and because Styrofoam consists mainly of air, when it dissolves in acetone it completely loses its structure. The styrofoam will dissolve in the acetone much like sugar dissolves in hot water. Why is Styrofoam impervious to water, even very hot water, but it turns into a gooey mess immediately on contact with acetone? Styrofoam dissolves in acetone in a similar way to how sugar dissolves in water. Science Fair Project Ideas for Kids, Middle & High School Students, University of Illinois Urbana-Champaign: Polymers, Polymer Properties Database: Polystyrenes. Styrofoam is made of polystyrene foam. So my question is why does acetone dissolve styrofoam when they appear to be a mix of polar/non-polar? : Hi guys! Acetone will not make Styrofoam hard. And, because styrofoam is mostly pockets of air, when the bonds are broken the air can escape. The air in the foam leaves, and because Styrofoam consists mainly of air, when it dissolves in acetone it completely loses its structure. Gather materials 2. How then does acetone reduce this substance to a blob of goo? Styrofoam is made of polystyrene foam. The acetone splits up the long chain of molecules, and the air disappears, causing the volume to shrink radically. MATERIALS 14 pieces of Styrofoam, each weighing 0.3 grams Acetone A larger container Timer Calculator. The acetone splits up the long chain of molecules, and the air disappears, causing the volume to shrink radically. Simply so, why does acetone dissolve Styrofoam? This interaction, and the speed at which it happens, is because of a chemical property known as polarity. Acetone is an organic compound with the formula (CH3)2CO. Acetone dissolves the Styrofoam cup. Do the experiment in a fume hood or well-ventilated room, and wear safety glasses and gloves. I mean, if you take gasoline and put in a styrofoam cup it will do the same thing, but you don't recommend taking gasoline internally, at least I hope you don't LOL. In this week’s video, we team up with chemistry professor Matt Hartings, Ph.D., to explain this weird phenomenon. When combined the Styrofoam seems to disappear inside the acetone. The acetone splits up the long chain of molecules, and the air disappears, causing the volume to shrink radically. These are the forces that determine the temperature at which a substance melts or boils. read more. It is a physical rather than a chemical reaction. Some types of spray paint, as well as gasoline, will also dissolve Styrofoam. Acetone and Styrofoam! The air con­tained in the plas­tic foam leaves it, … Far BETTER than mere acetone & … How It Works . Source: thoughtco.com. You need: -Acetone -Styrofoam -A metal or glass container Safety advisory: Acetone fumes are flammable. To carry out an experiment with Styrofoam and acetone, all you need is a large bowl or measuring glass. Observe the reaction between the acetone and the Styrofoam. Putting Styrofoam in acetone will dissolve how to do it is easy. If you have ever wanted to make something vanish as if by magic, all you need is acetone and Styrofoam. It is injected with gases during the manufacturing process and becomes extremely lightweight, with about 95 percent air. You can see a less-dramatic version of the same effect by dissolving other polystyrene items in acetone. This is because the intermolecular interactions between the acetone and the polystyrene makes it more thermodynamically stable for the two to exist as a solution rather than two separate distinct entities. In other words, the polystyrene dissolves in the acetone. Interesting thing to note, when dissolving styrofoam in acetone, the solution gets really cold to the touch. This can be used to point out that the packing peanuts are made mostly air with only a little polymer which is seen in the bottom of the flask. CP to ELI5. will dissolve Styrofoam with enough time. Styrofoam is mostly air so when a small amount of plastic dissolves, the … A colorless, flammable solvent, it mixes easily with water and evaporates quickly in air. Styrofoam vs Acetone! She writes about science and health for a range of digital publications, including Reader's Digest, HealthCentral, Vice and Zocdoc. When the polystyrene dissolves in the acetone, the air in the foam is released, causing it to look like you're dissolving this massive quantity of material into a small volume of liquid. It is a physical rather than a chemical reaction. Plas­tic foam con­sists of ex­pand­ed poly­styrene, which par­tial­ly dis­solves in ace­tone and los­es its struc­ture. The Styrofoam will dissolve in the acetone much like sugar dissolves in hot water. It is a physical rather than a chemical reaction. –Solvent—does the dissolving (acetone) ... styrofoam cup with acetate?) Styrofoam often makes up drink holders and insulating materials, as it is a poor conductor of heat. While Styrofoam does not decompose quickly or easily, acetone makes it seem to disappear in seconds. Remember that polystyrene is made up of many smaller molecules called monostyrene. The slightly charged parts of water molecules attract the ions in the ionic compounds and surround them, separating them from the crystal surface and drawing them into the solution. Like dissolves like. Only do this in a well-ventialted area. I have been doing research on this topic for a quite a while now .95% of people are concentrating in the fact that Styrofoam dissolve in Acetone. An experiment with acetone, Styrofoam and a glass bowl or measuring cup shows how much air is in Styrofoam and has pretty magical results. Acetone is a chemical that dissolves Styrofoam. METHOD 1. Pour the acetone into the container, then slowly add pieces of Styrofoam. Let it set overnight or even several days. This disappearance is in fact a dissolving, and the Styrofoam molecules become interspersed in the acetone. Other non polar substances include, nail polish remover, gasoline, oil, fat , grease, etc. This is why the non-polar polystyrene dissolves in acetone but not water and the polar starch molecules dissolve in water but not acetone. Basically, it looks like a huge amount of material is dissolving in a small amount of liquid. When the polystyrene dissolves in the acetone, the air in the foam is released. If you do not have acetone, you can use gasoline or just about any other organic solvent to easily dissolve Styrofoam. The video, uploaded by YouTube channel Let's Melt This, shows acetone — commonly used as nail polish remover — dissolving a Styrofoam cup on a plate. Styrofoam is made up of polystyrene foam. Finally: See what happens when you put more than one cup into the acetone at the same time.. Here’s What’s Happening! Styrofoam is actually a common name for a material called polystyrene, which is a polymer made up of a long chain of molecules. Another way of doing this is to pour acetone directly onto a piece of Styrofoam. The air in the foam leaves, and because Styrofoam consists mainly of air, when it dissolves in acetone it completely loses its structure. Common polystyrene products include disposable razors, plastic yogurt … If I increase the volume of acetone, then the Styrofoam will dissolve faster because there will be more liquid. The acetone breaks up the long chain of molecules, and the air goes away, hence the volume shrinks radically. Styrofoam dissolves in acetone in a similar way to how sugar dissolves in water. Once the styrofoam is fully dissolved it is stretchy and fun to play with. Styrofoam dissolves in acetone in a similar way to how sugar dissolves in water. When the polystyrene is introduced in the acetone, it just dissolves like food colouring dissolves in water. Dissolving Styrofoam or another polystyrene product in acetone is a spectacular demonstration of the solubility of this plastic in an organic solvent. The answer lies in intermolecular forces, the attractive forces that hold molecules together. A cup of acetone is enough to dissolve an entire bean bag's worth of styrofoam beads. No surprise here, its not really something to promote, seriously. Put a piece of Styrofoam in it 4. This dissolving and … Acetone can dissolve a plastic or Styrofoam cup. So, the correct question is: Why does acetone dissolve styrofoam? the Styrofoam cup turns into liquid form. While Styrofoam does not decompose quickly or easily, acetone makes it seem to disappear in seconds. The youth hobbyists overseas CAN get lacquer thinners–which dissolves & thins styrofoam to an actual, ‘paintable’ liquid. This is because acetone is a solvent that breaks down Styrofoam. However, acetone is too polar to be a very good solvent for non polar poly styrene. Even good solvents can take a while to dissolve a polymer. The air in the foam evaporates, and because Styrofoam consists mainly of air, it completely loses its structure. Copyright 2021 Leaf Group Ltd. / Leaf Group Media, All Rights Reserved. It also illustrates just how much air is in the Styrofoam. The acetone is a solvent that easily breaks down the polystyrene, releasing the little air pockets trapped inside and leaving very little residue at the end.
