Concentration of $OH^{-}$ decreases

Vedclass · Answer

(C) $NH_4OH$ is a weak base that dissociates as: $NH_4OH \rightleftharpoons NH_4^+ + OH^-$. When $NH_4Cl$ is added,it provides a common ion,$NH_4^+$. According to Le Chatelier's principle,the increase in the concentration of $NH_4^+$ ions shifts the equilibrium to the left. Consequently,the dissociation of $NH_4OH$ is suppressed,leading to a decrease in the concentration of $OH^-$ ions.
