What is the effect of adding a non-volatile solute to a solvent on its boiling point? (2019)
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: Learn about boiling point. The boiling point is the temperature at which a liquid turns into vapor.
Step 4: Recognize that adding a solute to a solvent changes its properties. When you add a non-volatile solute to a solvent, it affects how the solvent behaves.
Step 5: Understand boiling point elevation. This means that the boiling point of the solvent will increase when a non-volatile solute is added.
Step 6: Conclude that the presence of the solute makes it harder for the solvent molecules to escape into the vapor phase, thus requiring a higher temperature to boil.
