Answer the following question given this paragraph: The boiling point of a solution is higher than the boiling point of the pure solvent, but the opposite occurs with the freezing point. The freezing point of a solution is lower than the freezing point of the pure solvent. Think of this by assuming that solute particles interfere with solvent particles coming together to make a solid, so it takes a lower temperature to get the solvent particles to solidify. This is called freezing point depression. The equation to calculate the change in the freezing point for a solution is similar to the equation for the boiling point elevation:. Q: The boiling point of a solution is higher than the boiling point of the pure solvent, but the opposite occurs with this? Choices: - dissolving point - evaporation point - liquidity point - freezing point A:
freezing point
