Question

In the following diagram point, 'X' represents

Options

• Boiling point of solution

• Freezing point of solvent

• Boiling point of solvent

• Freezing point of solution

Answer 1

Freezing point of solution

Explanation:

An addition of a non-volatile solute causes the solvent's vapour pressure to drop.
since a nonvolatile solute solution's vapour pressure is lower than the solvent's vapour pressure. As a result, a solution's freezing point is lower than a solvent's.
So, the point 'X' represents the freezing point of the solution.
