The colligative properties of a solution depend on:

Which observation$(s)$ reflect$(s)$ colligative properties?
$(i)$ $A$ $0.5 \ m$ $NaBr$ solution has a higher vapour pressure than a $0.5 \ m$ $BaCl_2$ solution at the same temperature
$(ii)$ Pure water freezes at the higher temperature than pure methanol
$(iii)$ $A$ $0.1 \ m$ $NaOH$ solution freezes at a lower temperature than pure water
Choose the correct answer from the codes given below

Which of the following solutions boils at the highest temperature?

At low concentrations,the statement that equimolal solutions under a given set of experimental conditions have equal osmotic pressure is true for:

Colligative properties are used for the determination of:

Match the items given in Column-$I$ (method used for determining colligative property) and Column-$II$ (the corresponding colligative property) and find the correct order.

Column-$I$	Column-$II$
$A$. Beckmann method	$1$. Osmotic pressure
$B$. Ostwald-Walker method	$2$. Elevation in $B$.$P$.
$C$. Berkeley-Hartley method	$3$. Depression in $F$.$P$.
$D$. Landsberger method	$4$. Relative lowering of vapour pressure
