Solution

Q.
If $A_{2} B$ is 30% ionised in an aqueous solution, then the value of van’t Hoff factor $(i)$ is _____ $\times 10^{- 1}$ . [2025]

Ans.
(16)

$A_{2} B ⇌ 2 A^{+} + B^{2 -}$

$i = 1 + (n - 1) α$

One molecule of $A_{2} B$ dissociates into three particles, so $n$ = 3.

$α$ = 0.3 as per question.

$i = 1 + (3 - 1) \times 0.3$

$i = 1.6 = 16 \times 10^{- 1}$
