Question

Why is the elevation in boiling point of water different in the following solutions?
1) 0.1 molar NaCl solution

ii). 0.1 molar sugar solution.

​

Answer 1

The elevation in boiling point depends on the dissociation of particle in solution.

0.1 M NaCl will dissociate into Na+ and Cl-

0.1 M sugar solution will not dissociate.

The number of particle are more in NaCl, the elevation in boiling point is higher.
