In the equilibrium reaction AgCl(s) + 2NH3(g) 3 2 Ag(NH ) (aq) Cl (aq), an increase in the concentration of Cl –(aq) causes

A.AgCl(s) to decompose

B.AgCl(s) to precipitate✓ Correct

C.Ag(NH3)2

D.the NH3(aq) concentration to decrease

Explanation

According to the Le-Chatelier’s principle, when concentration of - Cl is increased in the reaction, the reaction will shift in backward direction to compensate for the increase in the concentration of one of the products. This will result in precipitation of AgCl. Hence, option (b) is the correct answer.
