Question

CaCl2 is used to clear snow from roads in hill stations.

(c)
The freezing point depression of 0.01 m NaCl is nearly twice that of
0.01 m glucose solution.

Answer 1

Explanation:

When each solute was added (NaCl and CaCl2), the boiling point of the 100 g of water slightly increased; with a larger amount of solute came a larger increase in the boiling point.

I

The concentration of solute particles in this case becomes approximately 0.2 M which is twice the concentration of glucose solution. Consequently, freezing point depression of NaCl solution is also approximately twice that of glucose solution
