(C) The chemical formula of potash alum is $K_2SO_4 \cdot Al_2(SO_4)_3 \cdot 24H_2O$,which can be written as $K_2Al_2(SO_4)_4 \cdot 24H_2O$.In this formula,the cations are $K^+$ and $Al^{3+}$,totaling $2 + 2 = 4$ cations.The anions are $SO_4^{2-}$,totaling $4$ anions.The number of water molecules is $24$.Thus,the ratio of cations : anions : water molecules is $4 : 4 : 24$.Simplifying this ratio by dividing by $4$,we get $1 : 1 : 6$.

The ratio of the number of cations,anions,and water molecules respectively in potash alum is:
