Problem

HgCl2\mathrm{HgCl}_2 is a covalent compound sparingly soluble in water. Its solubility increases on addition of chloride ions due to: (1) Common-ion effect (2) Formation of complex [HgCl4]2−[\mathrm{HgCl}_4]^{2-} (3) Weakening of Hg\mathrm{Hg}-Cl\mathrm{Cl} bonds (4) Strong ion-dipole forces
