What is the reaction between sodium thiosulphate and iodine?
This clock reaction uses sodium, potassium or ammonium persulfate to oxidize iodide ions to iodine. Sodium thiosulfate is used to reduce iodine back to iodide before the iodine can complex with the starch to form the characteristic blue-black color. Iodine is generated: 2 I − + S 2O2−8 → I 2 + 2 SO2−4.
Does thiosulfate remove iodine?
The removal of iodine is making by using 5% HYPO – SODIUM THIOSULFATE. Find in attach, a note about preparing and using of 5% HYPO – SODIUM THIOSULFATE. As well as, find below a link on a patent about this removal. You should remove the iodide by several water washes with water as it was suggested by Sudarsan.
