Question

The no. of mol. of the independent species present in one mole of potash alum:

• A. 32
• B. 16
• C. 38
• D. 64

Answer 1

The correct option is A 32

Potash alum can be chemically represented by the formula $K_{2}S{O}_4.A{l}_2(S{O}_4{)}_3.24H_{2}O$ which contains 2 moles of $K^{+}$, 2 moles of $A{l}^{3+}$, 4 moles of $S{O}_4^{2-}$ and 24 moles of $H_{2}O$ in each mole.

That is total of 32 no. of moles of the independent species present in one mole of potash alum.
