D. 30
The answer is D. 30 percent
If in the silver chloride solution we add NaCl then concentration of silver ions decreases, and the concentration of Chloride ions increases.
According to this law, when any external stress is applied in the equilibrium state then the reaction will shift on those side where the stress will reduces.
If in the silver chloride solutions then in the solution silver and chloride ions are present, and then when we add sodium chloride to that solution then it also dissociates into sodium and chloride ions. Then as a result of which concentration of chloride ions increases and to maintain the change equilibrium will shift towards the reactant side as a result of which concentration of silver ion decreases.
Hence, concentration of silver ions decreases, and the concentration of Chloride ions increases.
