Question

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

• A. 1
• B. 0.5
• C. 2.0
• D. 3

Answer 1

Answer: (C)

2.0

Answer 2

Vont’s Hoff factor $(i)$ $= \frac{\text{experimental C.P.}}{\text{Calculated C.P.}}$

$= 1 - \alpha + x\alpha + y\alpha,$ for KCl it is = 2 and for sugar it is equal to 1.
