“Acetone versus polystyrene foam” experiment
A huge bar of polystyrene foam dissolves in a few milliliters of acetone
Did you know that polystyrene foam dissolves in acetone?! Here’s a simple experiment which you can amaze your friends with.
Wear protective glasses and gloves. The experiment should be conducted in a well-ventilated room.
Reagents and equipment:
- acetone 10 ml;
- polystyrene foam;
- Petri dish.
Acetone is a good solvent. Polystyrene foam consists of foamy polystyrene, a material which partially dissolves in acetone and loses its structure. The air contained in the polystyrene foam is released, and its volume decreases drastically. All that is left is a thick and sticky mass of acetone and large polystyrene molecules.
