Karl Fischer titration is a classic titration method in chemical analysis that uses coulometric or volumetric titration to determine trace amounts of water The principle of Karl Fischer titration is based on the oxidation reaction between iodine and sulphur dioxide. Water reacts with iodine and sulphur dioxide to In the Coulometric Karl Fischer Titration the iodine is electrolytically generated. The amount of idodine added to the sample is determined by measuring theThe principle of Karl Fischer titration is completely based on the oxidation reaction between sulphur dioxide and iodine. Water reacts with sulphur dioxide 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 Karl Fischer titration is a widely used analytical method for quantifying water content in a variety of products. The fundamental principle behind it is called Karl Fischer titration. Abbreviations: KF or KFT. • It remains the primary method of water content determination used worldwide by:. Theory and Practice of its rapidity, accuracy and ease of use is Karl Fischer titration. Originally pyridine was used as the neutralising base.
