Chemistry - Redox Reactions Question with Solution | TestHub

As in a disproportionation reaction both oxidation & reduction takes place simultaneously .
Here$\mathrm{C}\mathrm{l}{\mathrm{O}}^{-}$is reduced into$\mathrm{C}{\mathrm{l}}^{-}$and simultaneously oxidised into$\mathrm{C}\mathrm{l}{\mathrm{O}}_3^{-}$.
$3\mathrm{C}\mathrm{l}{\mathrm{O}}^{-}\left(\mathrm{a}\mathrm{q}\right)\to \mathrm{C}\mathrm{l}{{\mathrm{O}}_3}^{-}\left(\mathrm{a}\mathrm{q}\right)+2\mathrm{C}{\mathrm{l}}^{-}\left(\mathrm{a}\mathrm{q}\right)$
