How do the boiling point and freezing point of a solution of water and calcium chloride at standard pressure compare to the boiling point point and freezing point of water at standard pressure

The boiling point of a  solution of water and calcium chloride is higher than the boiling point of water at standard pressure.

The boiling point if a solution is a colligative property. Colligative properties depend on the number of particles in solution. Other coligative properties include;

Hence, the boiling point of a  solution of water and calcium chloride is higher than the boiling point of water at standard pressure because impurities increases the boiling point of a substance.
