Question

Using salt and ice to make ice cream is an example of:A. Vapor pressure loweringB. Freezing point depressionC. Freezing point elevationD. Boiling point elevation

Answer 1

1) Dissolving a solute into a liquid.

When a pure solvent is freezing, the molecules become more ordered. This is due to the intermolecular forces. If we dissolve a solute, the ordering is disrupted causing the freezing point to get lowered.

B. Freezing point depression.
