Why is the elivation in boiling point of water different in the following solution?
(i) 0.1 molar NaCl solution.
(ii) 0.1 molar sugar solution.
solution:
The elevation in boiling point depend on the dissociation of particle in solution.
0.1 M NaCl will dissociate into Na+ and CI– whereas 0.1 M sugar solution will not dissociate. The number of particles are more in NaCl, the elevation in boiling point is higher.
