If van't Hoff factor of monofluoroacetic acid in water is $1 \cdot 076$. What is it's degree of dissociation?
- $0.76$
- $0.076$
- $0.924$
- $0.538$
Solution
$\mathrm{i}=1.076, \quad \alpha=?$
$\mathrm{CH}_{2} \mathrm{FCOOH} \rightleftharpoons \mathrm{CH}_{2} \mathrm{FCOO}^{-}+\mathrm{H}^{+}$
$\therefore \mathrm{n}=2$
$\alpha=\frac{i-1}{n-1}=\frac{1.076-1}{2-1}=0.076$
