Question

Accepted Answer

Karl Fischer process is a method for measuring moisture content in a sample.

Karl Fischer process is widely used in the pharmaceutical, chemical, and food industries.
It involves the reaction between water and iodine in the presence of sulfur dioxide.
The amount of iodine consumed in the reaction is proportional to the moisture content.
The process can be performed using volumetric or coulometric titration.
It is a sensitive and accurate method for moisture determination.

Accepted Answer

Karl Fischer Titration Procedure

The Karl Fischer titration experiment can be performed in two different methods. They are

Volumetric determination – This technique is suitable to determine water content down to 1% of water. The sample is dissolved in KF methanol and the iodine is added to KF Reagent. The endpoint is detected potentiometricall

Coulometric determination – The endpoint is detected in this experiment electrochemically. Iodine required for KF reaction is obtained by anodic oxidation of iodide from solution
