Vedclass · Answer

(C) The general formula for alum is $M_{2}SO_{4} \cdot M'_{2}(SO_{4})_{3} \cdot 24H_{2}O$,where $M$ is a monovalent cation (e.g.,$K^+$,$NH_4^+$) and $M'$ is a trivalent cation (e.g.,$Al^{3+}$,$Fe^{3+}$).$A$ pseudo alum has the general formula $MSO_{4} \cdot M'_{2}(SO_{4})_{3} \cdot 24H_{2}O$,where $M$ is a divalent cation (e.g.,$Mn^{2+}$) and $M'$ is a trivalent cation (e.g.,$Al^{3+}$).Therefore,$MnSO_{4} \cdot Al_{2}(SO_{4})_{3} \cdot 24H_{2}O$ is a pseudo alum.
