People add sodium chloride to water while boiling eggs. This is to increase the boiling point.
- If we add some volatile solid solute that is NaCl to water its vapour pressure decreases.
- The temperature at which vapour pressure is equal to external pressure is called the boiling point.
- So, as the vapour pressure decreases boiling point of the water increases and the eggs boil at a faster rate.
- Hence the correct option is b.
