Q67 / 180 · NEET 2016 (Phase 2) · Chemistry

The van't Hoff factor $(i)$ for a dilute aqueous solution of the strong electrolyte barium hydroxide is

A
$0$
B
$1$
C
$2$
Correct answer
D
$3$

Solution

B a {(O H)}_{2} ⟶ B a^{2 (+)} + 2 O H^{(-)}

∴

van't Hoff factor

= 1 + 2 = 3

.

Hence, the correct answer is option: 'D'.
