To `10 mL` of `1 M BaCl_(2)` solution `5mL` of `0.5 M K_(2)SO_(4)` is added. `BaSO_(4)` is precipitated out. What will happen?

Options

A. Freezing point will increase.
B. Boiling point will increase.
C. Freezing point will lower down.
D. Boiling point will lower down.

Answer

B, C

Explanation

Adding `K_(2)SO_(4)` into `BaCl_(2)` solution will result into precipitation of `BaSO_(4)` which is non-volatile, and therefore boiling point of solution will be increased and its freezing point will decrease.
