heat of solution → The overall energy change that occurs during the solution formation process.
miscible → Describes two liquids that can be mixed together but separate shortly after you cease mixing them.
mole fraction → The ratio of the number of moles of solute in solution to the total number of moles of solute and solvent.
freezing point depression → The temperature difference between a solution's boiling point and a pure solvent's boiling point.
suspension → A type of heterogeneous mixture whose particles settle out over time and can be separated from the mixture by filtration.
