Various analytical methods can estimate the concentration of sodium chloride (NaCl) in a sample. One of the most common methods for estimating sodium chloride is titration. In this method, we use a standard solution of silver nitrate (AgNO3) as the titrant, and the formation of a white precipitate of silver …
Fajans Method in Precipitation Titrations
The Fajans method, also known as the adsorption indicator method, is a classical technique that scientists use to determine chloride (Cl⁻) and bromide (Br⁻) ions in a solution. This method is based on the adsorption of an indicator ion onto the surface of the precipitate, leading to a visible color …
Modified Volhard’s titration
Modified Volhard’s titration is a variation of the classical Volhard titration method, which scientists use to determine the concentration of halide ions in a solution. Researchers value this modification, especially when they cannot apply the classical Volhard method due to the presence of interfering substances that can react with silver …
