(C) When $BaCl_2$ is added to a solution containing sulphate ions $(SO_4^{2-})$,a white precipitate of barium sulphate $(BaSO_4)$ is formed.The reaction is: $Ba^{2+}(aq) + SO_4^{2-}(aq) \rightarrow BaSO_4(s)$.This white precipitate of $BaSO_4$ is insoluble in dilute $HCl$,which confirms the presence of the sulphate radical.Therefore,compound $A$ must be a sulphate.
