Vapour pressure at $298 	ext{ K}$ : Salt water < Pure water

Vedclass · Answer

(D) $1$. Osmotic pressure $(\pi = iCRT)$: For $0.1 	ext{ M NaCl}$, $i=2$, so $\pi$ is higher than $0.1 	ext{ M Urea}$ $(i=1)$. Option $A$ is incorrect.$2$. Concentration: $2 	ext{ M}$ is much higher than $2 	ext{ ppm}$. Option $B$ is incorrect.$3$. Elevation in boiling point $(\Delta T_b = i K_b m)$: For $0.02 	ext{ M NaCl}$, $i=2$, so $\Delta T_b$ is higher than $0.02 	ext{ M Urea}$ $(i=1)$. Option $C$ is incorrect.$4$. Vapour pressure: Adding a non-volatile solute to a solvent lowers the vapour pressure. Thus, salt water has lower vapour pressure than pure water. Option $D$ is correct.

Which of the following is $CORRECT$ with respect to the property mentioned against it?
