Concentration of sulphide ions is lowered by formation of the weak acid $H_2S$

(D) The solubility of $MnS$ in dilute $HCl$ occurs because the sulphide ions $(S^{2-})$ react with the $H^+$ ions from $HCl$ to form the weak acid $H_2S$. $MnS(s) + 2H^+(aq) \rightleftharpoons Mn^{2+}(aq) + H_2S(aq)$. This reaction removes $S^{2-}$ ions from the solution,shifting the equilibrium to the right according to Le Chatelier's principle,thereby dissolving the $MnS$.
