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). 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.

Iodometric titrations

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 … Web1 dec. 2000 · The concentration of sulphide obtained by ISE for all the six tannery effluent samples has been tabulated along with those of iodimetry (Table 1).The variation in the results between the two techniques is quite appreciable indicating that certain modifications, especially in the ISE technique are required before these samples can be accurately … crypto-rating.com review

All About Iodometry Titration

WebLecture 1: Introduction to iodometric and iodimetric titrations When a reducing analyte is titrated with iodine (the titrant), the method is called iodimetry. Example: Quantification of Ascorbic Acid (Vitamin C) C 6 H 8 O 6 + I 2 → CçH 6 O 6 + 2 I- + 2 H+ Iodine rapidly oxidizes ascorbic acid, C 6 H 8 O 6 , to produce dehydroascorbic acid, C ...
