This method was originally developed in the 1930s by German chemist Karl Fischer. Karl Fischer titration is based on a 1:1 reaction between iodine and water in the presence of sulfur dioxide and a base. Below is the 2-step mechanism of the reaction: . Determination of water content using volumetric Karl Fischer titration is based on theThe different ways of producing iodine can be divided into the coulometric method and the volumetric method. Karl Fischer Titration Principle. The KF reaction is based on an earlier reaction called the Bunsen reaction, in which sulfur dioxide is oxidized by iodine and consumes water in the oxidation process. The initial response is as follows: The AQ-300 Karl Fischer Coulometric Titrator includes six built-in calculation modes for evaluating solid, liquid, and gas samples.
