Common ion effect

Vedclass · Answer

(A) $NH_4OH$ is a weak base that dissociates as: $NH_4OH \rightleftharpoons NH_4^+ + OH^-$. When $NH_4Cl$ is added,it dissociates completely as: $NH_4Cl \rightarrow NH_4^+ + Cl^-$. The increase in the concentration of $NH_4^+$ ions (common ion) shifts the equilibrium of $NH_4OH$ to the left according to Le Chatelier's principle,thereby suppressing its dissociation. This phenomenon is known as the common ion effect.

When $NH_4Cl$ is added to $NH_4OH$ solution,the dissociation of $NH_4OH$ is reduced. This is due to:
