Question

The following equilibrium exists in aqueous solution, $CH_3COOH$ $CH_3COO$ – + H + if dil. HCl is added, without change in temperature, the

Correct answer: B. 3 CH COOH is a weak acid, in the presence of HCl (strong acid) its dissociation is suppressed (common ion effect). This causes 3 CH COO ions to associate with H thus decreasing the acetate ion’s concentration in solution according to Le Chatelier’s principle.
