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
