Here statement B is incorrect as its aqueous solution is acidic in nature, due to hydrolysis of$\mathrm{A}{\mathrm{l}}_2(\mathrm{S}{\mathrm{O}}_4{)}_3.$However,${\mathrm{K}}_2\mathrm{S}{\mathrm{O}}_4$does not hydrolyse. Potash alum is${\mathrm{K}}_2\mathrm{S}{\mathrm{O}}_4.\mathrm{A}{\mathrm{l}}_2(\mathrm{S}{\mathrm{O}}_4{)}_3.24{\mathrm{H}}_2\mathrm{O}$which is used in dyeing industry and on heating, it melts in its water of crystallization.
