In comparison to a 0.01 M solution of glucose, the depression in the freezing point of a 0.01 M MgCl2 solution will be:
| 1. | Same | 2. | About twice |
| 3. | About three times | 4. | About six times |
As we know depression in freezing point is directly related to van't Hoff factor (i) according to which greater the value of i greater will be the depression in freezing point.

0.01 M glucose 0.01 M MgCl2 |
1 3 |
Hence, depression in freezing point of glucose is about 3 times of glucose.
