Iodometry Definition & Meaning Merriam-Webster Medical

WebThe iodine content in food salt is generally determined qualitatively using rapid test kits or quantitatively by iodometric titration (reference method). Spectrophotometric analysis is one of the recent developed quantitative methods, which has the advantage of being simple, robust and more convenient for the laboratory technician. However, there are few … WebA new method to determine both sodium chlorite and sodium hypochlorite in mixtures of the two by two-step iodometry is described. When hypochlorite reacts with potassium iodide in the presence of sodium bicarbonate, iodine is liberated immediately. In the case of chlorite, however, the reaction does not proceed under these conditions. WebThe iodometry method showed % RSD= 1,2402% for n=15. The results of t-test on both methods showed no significant difference.
