WebThiosulfate was oxidized to tetrathionate while the iodine was reduced to iodide ions according to the reaction: 2 S 2 O 3 2-+ I 2 → S 4 O 6 2-+ 2I. Iodine did not accumulate in the reaction vessel as it was rapidly consumed by the second reaction. Once the second reaction had completely consumed thiosulfate, iodine began to accumulate. WebThe negative charge in the I 3- ion is formally distributed over the three iodine atoms, which means that the average oxidation state of the iodine atoms in this ion is - 1 / 3. In the S 4 O 62- ion, the total oxidation state of the sulfur atoms is +10. The average oxidation state of the sulfur atoms is therefore +2 1 / 2.
