Why does acetone dissolve in water?

Answer 1

Acetone will float in water because it has a lower density than water. A few other liquids which will float on water are: ethanol, ether, methylated spirits and olive oil. Some that will sink in water are: chloroform and Mercury.

Answer 2

Acetone and water are miscible in all proportions. That means they dissolve in each other to an unlimited extent.

Answer 3

Acetone is a polar molecule, which gives it a strong intermolecular attraction to water, which is very polar. As a result, acetone is fully soluble in water.

Answer 4

Acetone is miscible in water because it can form hydrogen bonds with water molecules. This allows acetone to mix uniformly with water at a molecular level, leading to its dissolution in water.
