The percentage dissociation of a salt (MX3)\left(\mathrm{MX}_3\right) solution at given temperature (van't Hoff factor i=\mathrm{i}= 2) is ______ % (Nearest integer)

Correct answer

0

Step-by-step solution

MX3→M+3+3X⊖\mathrm{MX}_3 \rightarrow \mathrm{M}^{+3}+3 \mathrm{X}^{\ominus}
i=1+(n−1)αi=1+(4−1)α=2\begin{aligned} & \mathrm{i}=1+(\mathrm{n}-1) \alpha \\ & \mathrm{i}=1+(4-1) \alpha=2\end{aligned}
α=13=33.33%≈33%\alpha=\frac{1}{3}=33.33 \% \approx 33 \%
