Abstract

Abstract:

Colligative properties of dilute strong electrolyte solution, i.e., freezing point depression, boiling point elevation and osmotic pressure, are discussed. As an example, the freezing point depression equation of dilute strong electrolyte solution is derived with the help of Gibbs-Duhem equation. This equation is verified with the freezing point depression experiments of aqueous sodium chloride solutions.

Key words: Strong electrolyte, Dilute solution, Colligative property, Freezing point depression, Boiling point elevation, Osmotic pressure
