Vedclass · Accepted Answer

The vapour pressure of a solution containing a non-volatile solute is lower than that of the pure solvent at any given temperature.

Vedclass · Answer

(B) Osmotic pressure is a colligative property,not osmosis itself. Thus,statement $A$ is incorrect.The vapour pressure of a solution containing a non-volatile solute is lower than that of the pure solvent due to the decrease in the number of solvent molecules at the surface. Thus,statement $B$ is correct.Osmotic pressure is a colligative property dependent on the number of particles. $NaCl$ dissociates into $2$ ions ($Na^+$ and $Cl^-$),while sucrose does not dissociate. Therefore,the osmotic pressure of $0.1 \ M$ $NaCl$ is higher than $0.1 \ M$ sucrose. Thus,statement $C$ is incorrect.The boiling point of a solution containing a non-volatile solute is higher than that of the pure solvent (elevation in boiling point). Thus,statement $D$ is incorrect.

List-$I$	List-$II$
$A$. van't Hoff factor,$i$	$I$. Cryoscopic constant
$B$. $k_{f}$	$II$. Isotonic solutions
$C$. Solutions with same osmotic pressure	$III$. $\frac{\text{Normal molar mass}}{\text{Abnormal molar mass}}$
$D$. Azeotropes	$IV$. Solutions with same composition of vapour above it

Identify the correct statement from the following properties.

What is boiling point? What is freezing point?

The ionization constant of a monobasic acid $HA$ is to be determined. If a $0.025 \ m$ aqueous solution of the acid freezes at $-0.060 \ ^{\circ}C$,calculate the ionization constant $K_a$. (Assume molality = molarity and $K_f(H_2O) = 1.86 \ K \ kg \ mol^{-1}$).
