   How does Karl Fischer reagent titration work?

   • The reaction between the Karl Fischer reagent and water leads to a color change, which is detected by an indicator, marking the endpoint of the titration. By accurately measuring the volume of the Karl Fischer reagent required to reach this endpoint, chemists can calculate the moisture concentration in the sample.
