Vedclass · Answer

(C) Potash alum is $K_2SO_4 \cdot Al_2(SO_4)_3 \cdot 24H_2O$. In aqueous solution,it provides $SO_4^{2-}$ ions. Among the given cations,$Ba^{2+}$ reacts with $SO_4^{2-}$ ions to form a white precipitate of barium sulfate $(BaSO_4)$. The reaction is: $Ba^{2+}(aq.) + SO_4^{2-}(aq.) \rightarrow BaSO_4(s) \downarrow$ (white precipitate). Other cations like $Cu^{2+}$,$Zn^{2+}$,and $Ni^{2+}$ do not form precipitates with the sulfate ions present in potash alum under standard conditions.

Aqueous solution of which of the following cation gives a precipitate with potash alum?
