Question: In a solution of a non-volatile solute, how does the addition of solute affect the boiling point of the solvent?

Options:

Correct Answer: It increases the boiling point

Solution:

The addition of a non-volatile solute raises the boiling point of the solvent, a phenomenon known as boiling point elevation.

In a solution of a non-volatile solute, how does the addition of solute affect the boiling point of the solvent?

In a solution of a non-volatile solute, how does the addition of solute affect the boiling point of the solvent?

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.

Boiling Point Elevation – The phenomenon where the boiling point of a solvent increases when a non-volatile solute is added.
