Freezing Point Depression A phenomenon where adding a solute to a solvent lowers the solution's freezing point compared to the pure solvent. Normal Freezing Point The temperature at which a pure solvent solidifies before any solute is added. Freezing Point of Solution The temperature at which a solution solidifies after a solute is added to a solvent. Van't Hoff Factor A measure of the effect of a solute on colligative properties, indicating the number of particles the solute forms in solution. Freezing Point Depression Constant A solvent-specific constant used in calculating the change in freezing point when a solute is added. Molality A concentration unit defined as moles of solute per kilogram of solvent. Solute A substance dissolved in a solvent to form a solution, affecting the freezing point. Solvent A substance in which a solute is dissolved to form a solution, with a specific freezing point. Solution A homogeneous mixture formed when a solute is dissolved in a solvent. Water A common solvent with a normal freezing point of 0°C, often used in freezing point depression studies. Benzene An organic solvent with a specific freezing point and freezing point depression constant. Chloroform A solvent with a unique freezing point and freezing point depression constant, used in various applications. Ethanol An alcohol solvent with a distinct freezing point and freezing point depression constant.
