Q: What happens to the boiling point of a solvent when a non-volatile solute is added?
Solution: The boiling point of a solvent increases when a non-volatile solute is added due to boiling point elevation.
Steps: 5
Step 1: Understand what a solvent is. A solvent is a substance, usually a liquid, that dissolves a solute.
Step 2: Know what a non-volatile solute is. A non-volatile solute is a substance that does not easily evaporate at normal temperatures.
Step 3: Recognize that when a non-volatile solute is added to a solvent, it changes the properties of the solvent.
Step 4: Learn about boiling point elevation. This is the phenomenon where the boiling point of a liquid (the solvent) increases when a solute is added.
Step 5: Conclude that the boiling point of the solvent increases because the presence of the solute makes it harder for the solvent molecules to escape into the gas phase.
