Question

How the impurities present in a liquid affect its boiling point ?

Answer 1

• The boiling point of the solution increases on increasing the impurities.
• The water molecules present for vaporization during boiling decreases when impurities are added.
• Hence, a greater amount of heat energy would be required to vapourize the impure sample than the pure solution.
• Therefore, it leads to an increase in boiling point.
• However, the increase in boiling point depends on the nature of the impurities added to the solution.
