WebThe chlorine that exists in water as HOCl and OCl – is known as free chlorine. Free chlorine can kill bacteria, prevent algae growth, and oxidize iron to form a precipitate … 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.

WebIodometric Titration Principle. H2O2 oxidizes iodide to iodine in the presence of acid and molybdate catalyst. The iodine formed is titrated with thiosulfate solution, incorporating a starch indicator. H 2 O 2 + 2 KI + H 2 SO 4 → I 2 + K 2 SO 4 + 2 H 2 O I 2 + 2 Na 2 S 2 O 3 → Na 2 S 4 O 6 + 2 NaI.
