Van't Hoff factor of $\mathrm{Ca}\left(\mathrm{NO}_{3}\right)_{2}$ is
1 One
2 Two
3 Three
4 Four
Explanation:
$\mathrm{Ca}\left(\mathrm{NO}_{3}\right)_{2} \rightleftharpoons \mathrm{Ca}^{2+}+2 \mathrm{NO}_{3}^{-}$ It furnishes 3 ions per formula unit. So, its Van't Hoff factor is 3.

$\mathrm{K}_{2} \mathrm{HgI}_{4}$ is $40 \%$ ionised in aqueous solution. The value of its Van't Hoff factor (i) is
1 1.6
2 1.8
3 2.2
4 2.0
Explanation:
The ionisation of $\mathrm{K}_{2} \mathrm{HgI}_{4}$ is given as$\mathrm{K}_{2} \mathrm{HgI}_{4} \longrightarrow 2 \mathrm{~K}^{+}+\mathrm{HgI}_{4}^{2-}$ $i=1+(\mathrm{n}-1) \alpha$ $\alpha=0.4, \mathrm{n}=3$ So, $\quad i=1+2 \times 0.4=1.8$

Van't Hoff factor of aq $\mathrm{K}_{2} \mathrm{SO}_{4}$ at infinite dilution has value equal to
1 1

4 between 2 and 3
Explanation:
At infinite dilution, complete dissociation will take place. So, $\mathrm{K}_{2} \mathrm{SO}_{4} \rightarrow 2 \mathrm{~K}^{+}+\mathrm{SO}_{4}{ }^{2-}$ van't Hoff factor $=2+1=3$
