(a) The solution is saturated and at equilibrium.

(b) Addition of NaCl increases the concentration of Cl^– in solution.

(c) Addition of NaCl increases the concentration of Ag⁺ in solution.

(d) Addition of Ag⁺ results in the precipitation of AgCl.

(e) Addition of solid NaNO₃ to the solution without change in volume does not change [Ag⁺] or [Cl^–].
