Question

why does boiling point increases if we add salts in it

Answer 1

The water molecules need more energy to produce enough pressure to escape the boundary of the liquid. The more salt (or any solute) added to water, the more you raise the boiling point. The phenomenon depends on the number of particles formed in the solution.

Answer 2

because when we add salts there are impurities in it therefore its boiling point increases .......
