water measurement was introduced in 1935 when chemist Karl Fischer (KF) published his manuscript “New procedure for the determination of the water content in liquids and solids.” (K. Fischer; Angew. Chemie 1935, 48, 394). Karl Fischer titration, as it was to be known, could be followed by nearly any laboratory interested in water determination.
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.
