Vedclass · Answer

(C) The dissociation of a weak acid like $CH_3COOH$ is suppressed by the common ion effect.$CH_3COOH \rightleftharpoons CH_3COO^- + H^+$.$HCl$ provides $H^+$ ions,which suppresses the dissociation of $CH_3COOH$ due to the common ion effect.$CH_3COOK$ provides $CH_3COO^-$ ions,which also suppresses the dissociation of $CH_3COOH$ due to the common ion effect.$KCl$ is a neutral salt and does not provide any common ions ($H^+$ or $CH_3COO^-$).Therefore,the dissociation of $CH_3COOH$ is least suppressed (maximum) in the presence of $0.001 \, M \, KCl$ compared to the other options which contain common ions.
