$SO_3^{2-}$

Vedclass · Answer

(A) species is basic if it can accept a proton $(H^+)$ and a reducing agent if it can undergo oxidation (increase in oxidation state).$SO_3^{2-}$ acts as a base because it can accept a proton to form $HSO_3^-$.$SO_3^{2-}$ acts as a reducing agent because the sulfur atom is in the $+4$ oxidation state and can be oxidized to the $+6$ oxidation state (e.g.,in $SO_4^{2-}$).$SO_4^{2-}$ cannot be oxidized further,and $HSO_4^-$ is acidic in nature.

Column-$I$ [Type of reaction]	Column-$II$ [Example]
$I$. Intermolecular redox reaction	$A$. $CH_4 + 2O_2 \rightarrow CO_2 + 2H_2O$
$II$. Intramolecular redox reaction	$B$. $NH_4NO_2 \rightarrow N_2 + 2H_2O$
$III$. Disproportionation reaction	$C$. $2H_2O_2 \rightarrow 2H_2O + O_2$
$IV$. Comproportionation reaction	$D$. $KClO_3 \rightarrow KCl + \frac{3}{2}O_2$
