In the following reaction,assign the oxidation state for the underlined atom in the products of complete hydrolysis at $R.T.$:
$H_2\underline{S}_2O_6 + H_2O \longrightarrow H_2SO_3 + H_2SO_4$

Observe the following reaction:
$Cl_{2(g)} + 2OH^{-}_{(aq)} \rightarrow ClO^{-}_{(aq)} + Cl^{-}_{(aq)} + H_2O_{(l)}$
Identify the correct statements about this reaction:
$I$. $Cl_{2(g)}$ is oxidized to $ClO^{-}_{(aq)}$
$II$. $Cl_{2(g)}$ is oxidized to $Cl^{-}_{(aq)}$
$III$. $Cl_{2(g)}$ is reduced to $ClO^{-}_{(aq)}$
$IV$. $Cl_{2(g)}$ is reduced to $Cl^{-}_{(aq)}$
The correct answer is:
