Question

12 The boiling point of pure water is 100 oC. What likely be the effect on the
boiling point of water if 150 gram NaCl is added to one litre of water?​

Answer 1

Answer:

OPTION A: Boiling point of water will increase.

Answer 2

Answer:

The boiling point of water increases.

Explanation:

When impurity like salt ($NaCl$) is added to water, its boiling point rises.

This phenomenon is known as the boiling point elevation of the solvent. This means that there is an increase in the boiling point of the substance or solvent.

The impurities or solutes can alter the forces of attraction existing amongst the molecules of water or solvent. The impurities also try to overcome the vapor pressure for the water to boil. This causes an increase in boiling point.
