What happens when polystyrene is dissolved in acetone?
When the polystyrene dissolves in the acetone, the air in the foam is released. This makes it look like you’re dissolving a massive quantity of material into a small volume of liquid. The plastic dissolves in just about any organic solvent, not just acetone. Acetone is found in some nail polish removers.
Is polystyrene soluble in acetone?
Since polystyrene only contains carbon hydrogen bonds, it is nonpolar and will only dissolve in nonpolar solvents, because like dissolves like. This is why the non-polar polystyrene dissolves in acetone but not water and the polar starch molecules dissolve in water but not acetone.
What is the chemical reaction of acetone and Styrofoam?
It is a physical rather than a chemical reaction. The air in the foam leaves, and because Styrofoam consists mainly of air, when it dissolves in acetone it completely loses its structure. The acetone splits up the long chain of molecules, and the air disappears, causing the volume to shrink radically.
Why does acetone dissolve nonpolar?
Acetone is a small molecule that has very non-polar and polar properties simultaneously. Its polar C=O. bond makes it miscible (soluble) in water, while its non-polar methyl (CH3) groups can interact with non-polar compounds. This is why acetone can remove nail polish even though water can’t.
What common materials are soluble in acetone?
Acetone is used to dissolve other chemical substances and mixes readily with water, alcohol, dimethylformamide, chloroform, ether and most oils.

What happens when you mix acetone and gasoline?
But adding too much acetone to gasoline will speed up the flame burning too much, and adding too little will not influence, or speed up a little, the fuel burning.
What does gasoline dissolve?
As noted on Chevron’s Web site, while conventional gasoline can dissolve up to 150 parts per million of water at 70°F, the situation is different for gasoline oxygenated with 10% ethanol. This 90% gasoline/10% ethanol blend can dissolve up to 7,000 ppm of water at 70°F.
