Foam cups, bowls and containers are made of a lightweight but strong material – expanded polystyrene. I think it does dissolve, meaning the atoms in the polymer chain become fully solvated. Styrofoam often makes up drink holders and insulating materials, as it is a poor conductor of heat. Observe the reaction between the acetone and the Styrofoam. Materials for demo 039 1. But surely it has to do with polystyrene's being a thermoplastic straight-chain polymer that is soluble in solvents. You can use a large piece of Styrofoam, Styrofoam beads or even a Styrofoam cup. Yes, acetone dissolves Styrofoam. Styrofoam is actually a trade name, used generically to describe polystyrene foam, a polymer made of a long chain of molecules. Have you ever seen a foam cup appear to melt away in acetone? It is popular in plastics manufacturing, industrial cleaning products and some household liquids, such as nail polish remover. Some types of fish oil will dissolve Styrofoam very fast. Far BETTER than mere acetone & … So, the correct question is: Why does acetone dissolve styrofoam? How then does acetone reduce this substance to a blob of goo? A colorless, flammable solvent, it mixes easily with water and evaporates quickly in air. –Solvent—does the dissolving (acetone) ... styrofoam cup with acetate?) The Styrofoam does not completely disappear, even though it looks like it has. You can see a less-dramatic version of the same effect by dissolving other polystyrene items in acetone. Measure the time it takes for the Styrofoam to dissolve 5. The Styrofoam will dissolve in the acetone much like sugar dissolves in hot water. In this week’s video, we team up with chemistry professor Matt Hartings, Ph.D., to explain this weird phenomenon. Styrofoam is made of polystyrene foam. Do the experiment in a fume hood or well-ventilated room, and wear safety glasses and gloves. Since Styrofoam is mostly air, you may be surprised by how much (or, in the end, how little) foam will dissolve in the acetone. The air in the foam leaves, and because Styrofoam consists mainly of air, when it dissolves in acetone it completely loses its structure. Simply so, why does acetone dissolve Styrofoam? The … Once the styrofoam is fully dissolved it is stretchy and fun to play with. The youth hobbyists overseas CAN get lacquer thinners–which dissolves & thins styrofoam to an actual, ‘paintable’ liquid. 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. Always wear safety glasses, and wash your hands wel… This interaction, and the speed at which it happens, is because of a chemical property known as polarity. Like dissolves like. 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. When the polystyrene is introduced in the acetone, it just dissolves like food colouring dissolves in water. To carry out an experiment with Styrofoam and acetone, all you need is a large bowl or measuring glass. It is a physical rather than a chemical reaction. Take styrofoam beads, packing peanuts, chunks of styrofoam, or even a styrofoam cup and add it to the container of acetone. And, because styrofoam is mostly pockets of air, when the bonds are broken the air can escape. The reaction between Styrofoam and acetone shows how soluble this plastic is in an organic solvent and how much air is in Styrofoam. An experiment with acetone, Styrofoam and a glass bowl or measuring cup shows how much air is in Styrofoam and has pretty magical results.
