Expert Answer:


Following the aphorism, "like dissolves like", ionic compounds dissolve in polar solvents, especially those which ionize, such as water. They are usually appreciably soluble in other polar solvents such as alcohols, acetone.

Ionic compounds do not dissolve in nonpolar solvents such as diethyl ether or petrol (gasoline).

Ionic compounds dissolve in polar solvents like water because of the attraction between positive and negative charges
