Question

what happens to the freezing point of a solvent when a solute is added to it?
the freezing point decreases.
the freezing point increases.
the freezing point remains unchanged.

Explanation:

This question relates to the colligative property of freezing point depression in solutions. When a solute is added to a solvent, the freezing point of the solvent decreases. This is because the solute particles interfere with the solvent's ability to form a solid lattice, requiring a lower temperature for freezing.

Answer:

The freezing point decreases.
