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 change at the endpoint of … Read more
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 ions (Ag⁺). The modified Volhard … Read more
Volhard’s method, also referred to as the silver nitrate titration method, represents a classical precipitation titration technique for determining the concentration of halide ions in a solution. It resembles Mohr’s method but finds primary application in determining halides other than chloride ions, including bromide (Br⁻) and iodide (I⁻) ions.The key difference lies in choosing an … Read more
Chemists use precipitation titrations in chemical analysis to ascertain the concentration of an analyte (the substance under investigation) by prompting it to generate a solid precipitate through its reaction with a titrant (a solution of known concentration). This approach typically concentrates on specific ions or substances that can selectively precipitate under precise and controlled conditions. … Read more
