Adsorption indicators were first introduced by Fajans for the detection of endpoints of precipitation titrations, particularly in argentimetry. Any substance that forms a deformable anion or cation exhibiting different colors in solution and when adsorbed may be capable of functioning as an adsorption indicator in a precipitation titration. Since any large ion is... [Pg.2208]

Like Mohr s method, Fajans method is a direct titration method. It is based on the use of adsorption indicators. A small volume of an acetic acid solution and an adsorption indicator are added to the solution containing the halide to be determined. Then a silver nitrate solution is added. At the equivalence point, the precipitate suddenly turns colored and separates completely from the solution. [Pg.696]
