Webmixture. The thiosulfate ion does not react to any appreciable extent with any of the reactants. However, it does react very rapidly with the iodine (I 2) produced in reaction (1) according to the equation I + 2 S O 2– 2 I– + S O 2– (8) As the iodine produced by reaction (1) forms, it is immediately consumed by the thiosulfate ion.
