In a solution of a non-volatile solute, how does the addition of solute affect the boiling point of the solvent?
It decreases the boiling point
It has no effect on the boiling point
It increases the boiling point
It depends on the nature of the solute
The addition of a non-volatile solute raises the boiling point of the solvent, a phenomenon known as boiling point elevation.

Q
Q: In a solution of a non-volatile solute, how does the addition of solute affect the boiling point of the solvent?
Solution: The addition of a non-volatile solute raises the boiling point of the solvent, a phenomenon known as boiling point elevation.
Steps: 6
Step 1: Understand what a non-volatile solute is. A non-volatile solute is a substance that does not easily evaporate into a gas at normal temperatures.
Step 2: Know what boiling point means. The boiling point is the temperature at which a liquid turns into vapor.
Step 3: Recognize that when you add a non-volatile solute to a solvent (like water), it changes the properties of the solvent.
Step 4: Learn about boiling point elevation. This means that the boiling point of the solvent increases when a solute is added.
Step 5: Understand why this happens. The solute particles interfere with the solvent molecules, making it harder for them to escape into the vapor phase.
Step 6: Conclude that because of this interference, the temperature must be higher for the solvent to boil.
