Karl Fischer Titrator

Karl Fischer discovered that if sulfur dioxide is added in the excess the same reaction can be used for water determination by titration of the produced acids His base of choice was pyridine which was allegedly “just standing in the rack” In his honor the titration is named Karl Fischer titration (KF titration for short).
