VOLUMETRIC KARL FISCHER TITRATION Volumetric determination of water can be done with one-component or two-component titration. In one-component titration, all of the reactants needed for the reaction are present in a single solution. Two-component titration uses two solutions - one of them is a solvent that containsKarl Fischer titration for water determination is probably the best known and most widely used titration method. The reaction mechanism is well explored and there is a broad offering of suitable reagents and instruments to be used. The method is described in numerous regulations and guidelines with thousands of available applications.
