Vedclass · Answer

(C) Colligative properties depend on the number of particles in the solution.For a sugar solution,which is a non-electrolyte,the van't Hoff factor $(i)$ is $1$.For a $KCl$ solution,which is a strong electrolyte,it dissociates as $KCl \rightarrow K^+ + Cl^-$,so the van't Hoff factor $(i)$ is $2$.Since the colligative property is directly proportional to the van't Hoff factor $(i)$,the ratio of the colligative property of $KCl$ to that of sugar is $\frac{i_{KCl}}{i_{sugar}} = \frac{2}{1} = 2$.

The ratio of the value of any colligative property for a $KCl$ solution to that of a sugar solution of the same concentration is:
