Vedclass · Answer

(C) Colligative properties depend on the number of particles in the solution.For $KCl$ (a strong electrolyte),it dissociates as $KCl \rightarrow K^+ + Cl^-$,so the Van't Hoff factor $(i)$ is $2$.For sugar (a non-electrolyte),it does not dissociate,so the Van't Hoff factor $(i)$ is $1$.The ratio of the colligative property of $KCl$ solution to that of sugar solution is equal to the ratio of their Van't Hoff factors,which is $\frac{2}{1} = 2.0$.

The ratio of the value of any colligative property for $KCl$ solution to that for sugar solution is nearly
