Question

The ions present in the aqueous solution of potash alum are

• A. only $K^{+}$ and $A{l}^{3+}$
• B. only $K^{+}$ and $S{O}_4^{2-}$
• C. only $A{l}^{3+}$ and $S{O}_4^{2-}$
• D. All $K^{+},A{l}^{3+}$ and $S{O}_4^{2-}$

Answer 1

The correct option is D All $K^{+},A{l}^{3+}$ and $S{O}_4^{2-}$

Potash alum is $K_{2}S{O}_4.A{l}_2(S{O}_4{)}_3.24H_{2}O$
