Estimation of Sodium Chloride (NaCl) by Precipitation Titration

by

Introduction Sodium chloride (NaCl) is crucial in various fields such as pharmaceuticals, food, water analysis, and chemical industries. Its estimation is commonly performed using precipitation titration methods such as Mohr’s, Volhard’s, or Fajan’s methods. These methods involve titration of chloride ions (Cl−) with silver nitrate (AgNO3), forming a precipitate of silver chloride (AgCl). Methods for … Read more

Fajan’s Method

by

Introduction Fajan’s Method is a precipitation titration technique that uses adsorption indicators to detect the endpoint. Use it primarily for the determination of halide ions (Cl⁻, Br⁻, I⁻) and other anions by direct titration with silver nitrate (AgNO₃). This method is unique because it relies on the adsorption of an indicator onto the surface of … Read more
