Investigation of iodine liberation process in redox titration of potassium iodate with sodium thiosulfate Potassium iodate is often used as a reference material to standardize a sodium thiosulfate solution which is a familiar titrant for redox titrations. In th... T Asakai,A Hioki - 《Analytica Chi...
The difficulty was found to be in the storage container and it is postulated that iodate formation is responsible for the variation noted. Examples of discrepancies in analysis as a result of variation were demonstrated. It is recommended that additional precautions be observed in the storage of ...
Potassium iodateStandardization of sodium thiosulfate with potassium dichromate was discussed.Accuracy of the standardization method of sodium thiosulfate was evaluated.Sodium thiosulfate was assayed through two different paths based on coulometry.An appropriate iodine liberation condition in the standardization ...
