Webb15 feb. 2016 · The function of H2SO4 in Redox Titration is to get an acidic nature in the titration mixture. Explanation: here in this titration sulfuric acid H2SO4 is having the oxidation state of sulfur is +6,. This is the highest possible oxidation state of Sulphur which is found in its compounds. WebbIn iodometry the starch is added only after the color due to triiodide has begun to fade, i.e., near the endpoint, because starch can be destroyed in the presence of excess triiodide. In the first portion of this experiment a sodium thiosulfate solution is prepared and standardized with the primary standard potassium iodate. Iodate (IO3

Iodometry and Iodimetry, Daniele Naviglio « Analytical Chemistry
WebbIodometry is used in many experiments, whereas iodimetric titrations are used less frequently. Quantifying oxidising compounds is done with iodometry, whereas quantifying reducing agents is done with iodimetry. Conclusion. Although the names iodometry and iodimetry seem similar, they represent two distinct analytical chemistry methods. http://www.titrations.info/iodometric-titration Webbwhile shaking thoroughly, 17 ml of sulfuric acid solution (4.2).
