Freezing Point Depression of Sodium Chloride and Water

Freezing Point Depression of Sodium Chloride and Water

Freezing point depression is a phenomenon that occurs when a solute is added to a solvent, causing its freezing point to lower. In this practical investigation, we will explore the freezing point depression of water with different concentrations of sodium chloride (NaCl) and measure its impact on the freezing point. The experiment will involve preparing 50ml solutions of sodium chloride in water and measuring the temperature when the solution freezes over a range of salt concentrations from 1g to 20g per litre.
