Observe the following reaction $\mathrm{Cl}_2(\mathrm{~g})+2 \mathrm{OH}^{-}(\mathrm{aq}) \rightarrow \mathrm{ClO}^{-}(\mathrm{aq})+\mathrm{Cl}^{-}(\mathrm{aq})+\mathrm{H}_2 \mathrm{O}(\mathrm{l})$ Identify the correct statements about this reaction I. $\mathrm{Cl}_2(\mathrm{~g})$ is oxidized to $\mathrm{ClO}^{-}$(aq) II. $\mathrm{Cl}_2(\mathrm{~g})$ is oxidized to $\mathrm{Cl}^{-}(\mathrm{aq})$ III. $\mathrm{Cl}_2(\mathrm{~g})$ is reduced to $\mathrm{ClO}^{-}$(aq) IV. $\mathrm{Cl}_2(\mathrm{~g})$ is reduced to $\mathrm{Cl}^{-}(\mathrm{aq})$ The correct answer is
