Chemistry - Hydrogen and Its compound Question with Solution | TestHub

Hydrogen peroxide ($H_2{O}_2$) oxidizes thiosulphate ($S_2{O}_3^{2-}$) to sulphate ($S{O}_4^{2-}$). Oxidation involves an increase in oxidation state of sulfur.

The balanced reaction is:

$$S_2{O}_3^{2-}+4H_2{O}_2\to 2S{O}_4^{2-}+4H_{2}O$$
