Reaction between thiosulfate and iodine
Did you know?
WebThe relevant reaction is akin to the iodine reaction: thiosulfate reduces the hypochlorite (the active ingredient in bleach) and in so doing becomes oxidized to sulfate. The complete reaction is: 4 NaClO + Na2S2O3 + 2 … 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.
