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

The relative lowering of vapour pressure for $0.1 \ M$ aqueous solutions of $NaCl$,$CuSO_4$,and $K_2SO_4$ is in the ratio of...

When $HgI_2$ is added to an aqueous solution of $KI$,then the:

In which case is Raoult's law not applicable?

$pH$ of a $0.1 \ M$ monobasic acid is found to be $2$. Hence its osmotic pressure at a given temperature $T \ K$ is (in $RT$)

If $13.44 \ g$ of $CuCl_2$ is dissolved in $1 \ kg$ of water,calculate the elevation in boiling point of the solution. $[K_b = 0.5 \ K \ kg \ mol^{-1}$,molar mass of $CuCl_2 = 134.1 \ g \ mol^{-1}]$
