Questions & Step-by-Step Solutions

What happens to the freezing point of a solvent when a non-volatile solute is added?
  • 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 room temperature.
  • Step 3: Recognize that when you add a non-volatile solute to a solvent, it changes the properties of the solvent.
  • Step 4: Learn about freezing point depression. This is the process where the freezing point of a solvent decreases when a solute is added.
  • Step 5: Conclude that the freezing point of the solvent goes down because the solute disrupts the formation of ice.
