One of the reasons that solid CuSO4 dissolves in water is: a instantaneous dipole-induced dipole forces (dispersion or London forces) between the Cu2 and the SO42- ions b the ion-dipole forces between the ions and the water molecules c the electrostatic force of attraction between the Cu2 and the SO42- ions d the hydrogen bonding between the water molecules e instantaneous dipole-induced dipole forces (dispersion or London forces) between the water molecules
