- Methanol is used as a solvent in Karl Fischer titrations.
- Make a solution by mixing 170 mL of pyridine and 670 mL of methanol. Add 125 g of iodine to the solution and cool it. Take a 250 mL graduated cylin...
- The main difference between them is that: Volumetric method – the titrant is directly added to the sample with the help of a burette. Coulometric...
- The Karl Fischer titration is merely a means of measuring sample water content. Modern instruments, such as the Aquamax KF, apply the coulometric p...
- The volumetric standard for Karl Fischer titration is sodium tartrate dihydrate. It is stable and non-hygroscopic, under normal conditions. Sodium...
- The reaction has reached its termination point because the iodine is in abundance. For electrochemical indication of the end point, the most comple...
- The water equivalence factor F is determined according to the formula 0.1566 x w / v in mgs of H2O per ml of reagent, where W is the sodium tartrat...
