JEE Mains · Chemistry · STD 12 -1. Solution and colligative properties
The percentage dissociation of a salt \(\left(\mathrm{MX}_3\right)\) solution at given temperature (van't Hoff factor \(\mathrm{i}=\) 2) is ______ % (Nearest integer)
- A 11
- B 22
- C 33
- D 44
Answer & Solution
Correct Answer
(C) 33
Step-by-step Solution
Detailed explanation
\(\mathrm{MX}_3 \rightarrow \mathrm{M}^{+3}+3 \mathrm{X}^{\ominus}\) \(\begin{aligned} & \mathrm{i}=1+(\mathrm{n}-1) \alpha \\ & \mathrm{i}=1+(4-1) \alpha=2\end{aligned}\) \(\alpha=\frac{1}{3}=33.33 \% \approx 33 \%\)
