What is Karl Fischer titration?
In analytical chemistry, Karl Fischer titration is a classic titration method that uses coulometric or volumetric titration to determine trace amounts of water in a sample. It was invented in 1935 by the German chemist Karl Fischer. Today, the titration is done with an automated Karl Fischer titrator.
What is Karl Fischer's method?
This brochure presents a historical overview of the development of Karl Fischer’s method. It explains the chemical reaction as well as two major measuring techniques: volumetry and coulometry.
What is Kft titration?
KFT analysis is based on the modified Bunsen reaction, in which water reacts stoichiometrically with iodine in a suitable solvent and in the presence of an organic base . Depending on how iodine is provided, KFT methods can be divided into two classes, namely volumetric and coulometric Karl Fischer titrations (vFKT and cKFT).
Who invented water titration?
It was invented in 1935 by the German chemist Karl Fischer. Today, the titration is done with an automated Karl Fischer titrator. The elementary reaction responsible for water quantification in the Karl Fischer titration is oxidation of sulfur dioxide ( SO2) with iodine :
