What happens when a salt like copper sulphate react with react?

When a salt like copper sulfate in placed in water, the ionic bonds are broken and the ions (copper cation and sulfate anion) separate and become hydrated by the water molecules. This is the case of dissolution or dissolving. In the case of copper(II) sulfate, for example, CuSO4(s) + H2O(l) ==> Cu^2+(aq) + SO4^2-(aq)
