At higher altitude,the boiling point of water is $95\,^oC$. The amount of $NaCl$ added to $1\,kg$ of water $(K_b = 0.52\,K\,kg\,mol^{-1})$ in order to raise the boiling point of the solution to $100\,^oC$ (assume $90\%$ ionisation of $NaCl$) is .......... $g$.

The freezing point of a $0.05 \ m \ BaCl_2$ solution in water ($100 \%$ ionisation) is about $(K_f = 1.86 \ K \ kg \ mol^{-1})$. (in $^oC$)

The osmotic pressure of a $0.1 \ M$ solution of $NaCl$ and $Na_2SO_4$ will be:

Carnallite in solution in $H_2O$,shows the properties of

The van't Hoff factor $(i)$ for the reaction of $HNO_3$ with $H_2SO_4$ is:

When $9.45 \text{ g}$ of $ClCH_2COOH$ is added to $500 \text{ mL}$ of water,its freezing point drops by $0.5^\circ \text{C}$. The dissociation constant of $ClCH_2COOH$ is $x \times 10^{-3}$. The value of $x$ is ............... (Rounded off to the nearest integer) $[K_{f(H_2O)} = 1.86 \text{ K kg mol}^{-1}]$
