02. Water by KF
● Transfer about 50.0 mL of methanol into the titration vessel
● Switch on the instrument
● Adjust the speed for proper rotation of magnetic fish
● Neutralize the methanol by adding Karl Fischer reagent
● After reaching the end-point add about 5.0 mL of the test sample into
titration vessel and replace the cork.
● Fill the burette and start titration
● After getting the end-point note down the titre value
● Calculate the Water by KF as follows
Water by KF: Volume of KFR consumed X KFR factor
Volume of the test sample
● Perform the above operations twice
● Express the mean of these consistent values as Water by KF
