The effect of adding sodium chloride will be that of the common ion effect. Under the common ion effect, the solubility of a substance is reduced due to the disturbance of the solubility equilibrium by the addition of an ion that is already present. Therefore, the effect will be: 2) [Cl-] increases (since it is added), and [Pb+2] decreases (due to the common ion effect)
