Question

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

Answer 1

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

Step-by-step explanation:

Answer 2

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.
