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. WebIodometry. The term “iodometry” describes the type of titration that uses a standardised sodium thiosulfate solution as the titrant, one of the few stable reducing agents where …
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 … WebIn the iodometric analysis of oxidizing agents an equivalent amount of iodine is produced when the sample oxidizes potassium iodide in the presence of mineral acid. The …
WebIodometric methods depend on the following equilibrium: I2 + I − ⇌ I − 3. Since the solubility of I 2 in water is quite low, the formation of the tri-iodide ion, I 3 -, allows us to obtain useful concentrations of I 2 in aqueous solutions. The equilibrium constant for this reaction is approximately 700. WebIt is commonly used for measuring the concentration of chlorine in water as an example of what it can be used for. Iodide is oxidized by chlorine when the pH is below 8. A large amount of potassium iodide is added to a known sample amount in an acidic environment (pH is 4. More alkaline pH does not allow the reaction to complete).
