The following pictures represent solutions of CaCO3,which may also contain ions other than Ca2+ and CO32- which are not shown.Gray spheres represent Ca2+ ions and unshaded spheres represent CO32- ions. 
-If solution (1) is a saturated solution of CaCO3,which of solutions (1) -(4) represents the solution after a small amount of HNO3 is added and equilibrium is restored?
