Thus, the optimal pH range for the Karl Fischer reaction is from 5 to 8, and highly acidic or basic samples need to be buffered to bring the overall pH into that range. What are the two types of Karl Fischer Titration? 1) Volumetric KFT In volumetric Karl Fischer, iodine is added mechanically to a solvent containing the sample by the
Karl Fischer titration is used for many substances as a reference method, and is a chemical analysis based on the oxidation of sulfur dioxide by iodine in a methanolic hydroxide solution. . In the volumetric method a Karl Fischer solution containing iodine is added until the first trace of excess iodine is present. The amount of iodine .
The optimum pH range of the sample solution for efficient Karl Fischer titration is between pH 5.5 and 8. When the pH is greater than 8.5, the reaction rate increases due to chemical side reactions. . It is combined with either a coulometric or volumetric Karl Fischer titrator to determine the amount of water in the sample efficiently and .
1.1 This test method is intended as a general guide for the application of the volumetric Karl Fischer (KF) titration for determining free water and water of hydration in most solid or liquid organic and inorganic compounds.
