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 form sulphur trioxide and hydrogen iodide.
Karl Fischer titration is a widely utilized analytical method specifically designed to determine the moisture content in various substances. This titration technique relies on a chemical reaction between iodine and sulfur dioxide with water, a reaction integral in quantifying moisture levels accurately. [1-4]
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 .
