directly in the titration cell. Instead, in volumetric KF titrators, a burette injects the titrant into the titration cell. Coulometric titrators measures water contents that are much lower than the volumetric titrators (Section 3.2).[6] 3.1 | Volumetric KF The volumetric KF instrument consists of a titration vesselThe 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:Volumetric Karl Fischer titration (KF titration) is a selective method used to determine water content in pharmaceuticals. It involves the reaction between iodine, sulfur dioxide, and water molecules in the presence of a suitable solvent and base. The electric current monitored during the reaction is used to analyze the water content in the KF .
Karl Fischer (KF) titration is a widely accepted method for determining the water content in a sample, with volumetric Karl Fischer titration being the most used technique, measuring water content from 100 ppm to 100%. However, achieving accurate results can be challenging, as several factors can influence the outcome.
