Question

A saturated solution of $Ag_2CrO_4$ is present over its own solid precipitate. If additional $CrO_4^{2-}$ ions are introduced into the solution (e.g., by adding $K_2CrO_4$), this action will predominantly result in:

Prashant Kotian · Accepted Answer

Correct answer: B. Adding ions increases the concentration of the anion in the equilibrium. According to Le Chatelier's principle (Common Ion Effect), the system will shift backward to consume the added , precipitating more solid and thereby drastically decreasing the free concentration in the solution. remains constant as long as temperature is constant.
