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

1. 1
2. 0.5
3. 2
4. 2.5

KCl dissociates into 2 ions(K+ and Cl-) whereas sugar doesnot dissociate. Therefore, the ratio of the value of any colligative property for KCl solution to that for sugar solution is nearly 2 times.

Hence, option 3 is correct.
