The results in volumetric Karl Fischer titration are fluctuating – what are the reasons? Possible reasons: Improper stirring time and speed, if the stirring speed is too slow, the titration may also be too slow, irregular and over titration may occur. If stirring speed is too high then bubbles are formed in the solution which can falsify the .
