Water has a boiling point of 100°c. after salt is dissolved in water, the boiling point of the resulting solution is a) less than 100°c b) greater than 100°c c)equal to 100°c d)equal to 0°c

Option (B) is correct. The boiling point will be greater than 100°C

This phenomenon of increase in the boiling point of a liquid because of the addition of salt is called as elevation in boiling point.

Boiling point is a temperature at which the vapor pressure of the liquid becomes equal to the atmospheric pressure.When a non volatile salt is added to a liquid, its vapor pressure decreases. Thus we need to heat the liquid more for its vapor pressure to become equal to the atmospheric pressure. Thus the boiling point increases.

The correct answer is B i hope this helps you out :)
