Derivation and Experimental Verification of Colligative Equations of Dilute Strong Electrolyte Solution

Department of Chemistry and Chemical Engineering, School of Chemistry and Biological Engineering, University of Science and Technology Beijing, Beijing 100083, P. R. China

Received Date: 30 April 2018

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.
