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

the ion-dipole forces between the ions and the water molecules

Explanation:

Water is a polar molecule having a high dipole moment. This high polarity makes it a popular choice of polar solvent.

CuSO4 is an ionic compound composed of Cu^2+ and SO4^2-. When dissolved in water, the positive dipole in water interacts with the negative ion while the negative dipole in water interacts with the positive ion thereby causing the compound(CuSO4 ) to dissolve in water due to the ion-dipole forces between the ions and the water molecules.
