H2s titration
Webdetermined by titration with sodium thiosulfate, using starch as an indicator (Kolthoff and others, 1969). +1H S-2 + I 2 → S + 2I-1 H +1 I2 + 2S2O3-2 → S 4O6-2 + 2I-1 A blank is … 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. Scope of Application

A redox titration is a titration in which the analyte and titrant react through an oxidation–reduction reaction. As in acid–base titrations, the endpoint of a redox titration is often detected using an indicator. Potassium permanganate (KMnO₄) is a popular titrant because it serves as its own indicator in acidic solution.
