WebBasic Principles. Iodometry is commonly used to analyse the concentration of oxidizing agents in water samples, such as oxygen saturation in ecological studies or active chlorine in swimming pool water analysis. To a known volume of sample, an excess but known amount of iodide is added, which the oxidizing agents oxidizes iodide to iodine. WebTitrate the sample solution with thiosulfate until the solution becomes pale yellow. Introduce 5 drops of starch indicator, and titrate with constant stirring to the disappearance of the blue colour.
