    the solid copper(II) nitrate is used to dissolve in a test tube filled with half distilled water. The solid copper(II) nitrate ionize in water to form copper(II) ions and nitrate ion. Hence‚ a blue solution is formed due to the blue copper(II) ion present in the solution. When excess solid is added‚ the solution will become saturated and do not allow any solid to dissolve‚ so excess solid will remain in the solution. This is shows that the equilibrium between solid and aqueous copper(II) nitrate
