$0.1 \ M \ KCl$

Vedclass · Answer

(B) The solubility of $AgCl$ is governed by the common ion effect. In the presence of $0.1 \ M \ KCl$,the concentration of $Cl^{-}$ ions increases significantly. According to Le Chatelier's principle,the equilibrium $AgCl(s) \rightleftharpoons Ag^{+}(aq) + Cl^{-}(aq)$ shifts to the left,decreasing the solubility of $AgCl$. $KNO_3$ does not provide a common ion,and its effect on solubility is negligible compared to the common ion effect. Therefore,the solubility of $AgCl$ is minimum in $0.1 \ M \ KCl$.

In which of the following,the solubility of $AgCl$ will be minimum?
