The Karl Fischer titration is a traditional titration technique used in chemical research to identify minute amounts of water in a sample using coulometric or volumetric titration.
The Karl Fischer titration (hereafter referred to as KF) is widely used because it has a number of advantages over other techniques for determining moisture, including accuracy, speed, and selectivity.
Because water is consumed during the titration reaction, KF is selective for water. In contrast, measuring the mass lost during drying will reveal any volatile substance’s loss.
Yet, because of the strong redox chemistry (SO2/I2), redox-active components of the sample may interact with the reagents.
The Karl Fischer titration is a popular analytical technique for calculating the amount of water in various goods. The Bunsen Reaction between iodine and sulphur dioxide in an aqueous media is the basis for the basic idea behind it.
The KF reaction is based on the consumption of water in a buffered solution while sulphur dioxide is being oxidised by iodine.
When the titrating agent has reached a volume large enough to react with all of the water in the sample, the titration has reached its endpoint. Iodine and water are depleted in an equimolar ratio.
The discovery of excess iodine at the double platinum electrode, which serves as the indicator, results in a colour change that marks the reaction’s end point.
The Global Karl Fischer Titrator Market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
The method of Karl Fischer titration is used to gauge moisture content. Karl Fischer, a chemist, was the person who invented the method. It is based on a reagent that combines with water to create a compound that is not conductive.
Karl Fischer offers a method for precisely identifying a product’s water content. This method uses a titration cell to mix the reagent and solvent.
Reagent is released by the introduction of an electrical current when a sample is added to the titration cell and dissolved.
The amount of moisture is determined by the amount of current needed to convert the water. Coulometer is a common name for a Karl Fischer coulometric device.
