Vedclass · Answer

(C) The relative lowering of vapor pressure is a colligative property,which depends on the number of particles in the solution.For equimolar solutions,the vapor pressure decreases as the van't Hoff factor $(i)$ increases.$1$. $	ext{Glucose}$ is a non-electrolyte,so $i = 1$.$2$. $NaCl$ dissociates as $NaCl ightarrow Na^+ + Cl^-$,so $i = 2$.$3$. $Ba(NO_3)_2$ dissociates as $Ba(NO_3)_2 ightarrow Ba^{2+} + 2NO_3^-$,so $i = 3$.Since the number of particles is in the order $	ext{Glucose}  NaCl > Ba(NO_3)_2$.

When the vapor pressures of equimolar aqueous solutions of glucose,sodium chloride,and barium nitrate are compared,which order is correct?
