The reaction which involves oxidation, requires an oxidising agent.

S_{2} O_{3}^{2 -} \to S_{4} O_{6}^{2 -}

S is undergoing oxidation. Oxidation state of S changes form 2 to 2.5 and hence this reaction requires an oxidising agent.

$2 S_{2} O_{3}^{2 -} ⇌ S_{4} O_{6}^{2 -}$

$Z n^{2 +} ⇌ Z n$

$Cl O^{-} ⇌ C l^{-}$

$S O_{3} ⇌ S O_{4}^{2 -}$
