Abstract
In the invention, a back titration and titer determination can be made using a back coulometric titration. When the iodine exists in a solution put in the titration flask with electrolytic electrodes, a back coulometric titration is performed to produce iodine ions from the iodine at the anode of the electrolytic electrodes. Where the solution is a dehydrated solvent including a Karl Fischer reagent for a volumetric titration, the titer can be determined by the back coulometric titration. Where the solution is anolyte in which the iodine remains after the coulometric titration in the coulometric titration method, the water content in the sample is found from the quantity of electricity consumed by the coulometric titration and the quantity of electricity consumed by the back coulometric titration. Where the solution is anolyte in which the iodine remains by adding Karl Fischer reagent in the volumetric titration method, the water in the sample put in the titration flask is found from the added amount of Karl Fischer reagent and the quantity of electricity consumed by the back coulometric titration.
