Question

A liquid typically boils at 200 °C. If a soluble salt is added to the liquid, its new boiling point will be:

A) Greater than 200 °C
B) Less than 200 °C
C) 200 °C
D) Not enough info

Answer 1

The answer is A
When a impurity is introduced to a pure substance, its melting point falls and boiling point rises. Therefore the new pointing point is greater than 200
