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
Introduction Mohr’s method is a classical argentometric precipitation titration used for the quantitative determination of chloride (Cl⁻) and bromide (Br⁻) ions using silver nitrate (AgNO₃) as a titrant. Potassium chromate (K₂CrO₄) acts as an indicator, which helps detect the endpoint by forming a reddish-brown precipitate of silver chromate (Ag₂CrO₄). Principle of Mohr’s Method Mohr’s method … Read more
Introduction Precipitation titrations are a type of volumetric analysis in which the reaction between the analyte and the titrant results in the formation of an insoluble precipitate. These titrations are commonly used to determine the concentration of ions that form sparingly soluble salts with the titrant. The most common examples include the determination of halide … Read more
