Web27 okt. 2024 · Second important reaction used in the iodometry is reduction of iodine with thiosulfate: 2S 2 O 3 2-+ I 2 → S 4 O 6 2-+ 2I-In the case of both reactions it is better to avoid low pH. Thiosulfate is unstable in the presence of acids, and iodides in low pH can be oxidized by air oxygen to iodine. Both processes can be source of titration errors. WebImportantly, as the reaction produces diatomic iodine, the thiosulfate re-reduces the iodine back to iodide: 2S 2 O 3 2-+ I 2 → 2I – + S 4 O 6 2-This back and forth between iodide …
