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

Both the increase in the boling point and the depression on the freezing point are colliative properties.

This is, they are proportional to the number of particles dissolved in the solvent, which is measured by the molality of the solution and the factor i (Van'f Hoff).

The answer to the question is that 1) the boling point of a solution of water and calcium chloride at standard pressure will be higher than the normal boiling point of pure water, and 2) the freezing point of a solution of water and calcium chloride at standard pressure will be lower than the normal freezing point of pure water.

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;

Freezing pointVapor pressureOsmotic pressure

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.
