Freezing point depression measures the decrease in the freezing point of a solvent due to the presence of a solute. By understanding freezing point depression, we can determine the concentration or molar mass of a solution. The setup involves using thermometers in ice baths to measure the freezing point of solutions and pure solvents. Factors such as solvent properties and electrolyte presence influence the freezing point depression. This method has applications in molar mass determination, electrolyte identification, and intermolecular interaction studies. However, limitations include deviations in non-ideal solutions and inaccuracies with electrolyte solutions.
