Answer» Freezing-point depression is the decrease of the freezing point of a solvent on addition of a non-volatile solute. Examples include salt in water, alcohol in water, or the mixing of two solids such as impurities into a finely powdered drug. The freezing point Tf of a solution of a nonvolatile solute is lessthan that of the pure solvent. The change in freezing point DeltaTf (also called the freezing point depression, Td) is given by:Delta Tf = (Tf of pure solvent) - (Tf of solution) |
