Web2.2 Sulfide is reacted with an excess of iodine in acid solution, and the remaining iodine is then determined 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 treated exactly the same as the samples. The sulfide ...
Chlorine Titration with Sodium Thiosulfate - Mantech
Web14 mrt. 2024 · The reaction rate has been halved, but the amount of thiosulfate also has been halved, so you only need to make half the amount of iodine to combine with all the thiosulfate. If the sodium thiosulfate was not in solution A, but in a solution C, the result of 5. would be the same as in 4. WebA redox reaction occurs between iodine and thiosulfate ions: 2S2O32– (aq) + I2 (aq) → 2I–(aq) + S4O62– (aq) The light brown/yellow colour of the iodine turns paler as it is … how to save mcc command settings sims 4
