Is copper sulphate dissolved in water a physical change?

Technically, dissolution is quite different from dissociation. There is a difference in dissolution of sugar and dissociation of ionic compounds. The former is a physical change and the latter is not. Traditionally, chemical change can be associated to bond breaking and forming which results to new chemical species. read more

Dissolution is generally considered a chemical change. Remember physical changes change nointrinsic properties such as mass or volume and phase. When a molecule like copper sulphate is added to water it ionizes, or breaks apart into copper ions and sulphate ions. read more

When CuSO4 (copper sulfate) dissolves in H20 (water) you still have copper sulfate and water, so there is no chemical reaction. It is a physical change. You will have copper and sulfate ions, but if you boil the solution and catch the steam, you will end up with copper sulfate and water. read more

1. Copper (II) sulphate dissolving in water is a physical change, since you aren't producing a new chemical. 2. Sodium hydroxide to copper (II) sulphate solution produces a blue-green precipitate of copper (II) hydroxide, so this is a chemical change. read more
