Question

The boiling point of a pure substance does not get affected when an impurity is added to it.

Answer 1

Explanation:

This happens because the presence of impurities decreases the number of water molecules available to be vaporized during boiling. ... It is important to realize however, that impurities do not always increase boiling point, and, in certain rarer cases, can actually cause boiling point to decrease.
