As shown in Formula (1) below, the Karl Fischer method uses Karl Fischer reagent, which reacts quantitatively and selectively with water, to measure moisture content. Karl Fischer reagent consists of iodine, sulfur dioxide, a base and a solvent, such as alcohol.
I2+SO2+3Base+ROH+H2O ⇒ 2Base+HI+Base+HSO4R ······ (1)
As described below, this method can be used in both volumetric and coulometric titration systems.
