Question

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

Explanation:

This is a question about colligative properties in chemistry (a subfield of Natural Science). Colligative properties depend on the number of solute particles. When a solute is added to a solvent, the boiling point elevation phenomenon occurs. The solute particles interfere with the solvent's vaporization, requiring a higher temperature (higher boiling point) for the solvent to boil. So the boiling point of the solvent increases when a solute is added.

Answer:

B. The boiling point increases.
