Vedclass · Answer

(A) $1$. $A$ species is basic if it can accept a proton $(H^+)$.$2$. $A$ species is a reducing agent if it can be oxidized to a higher oxidation state.$3$. In $SO_3^{2-}$,the oxidation state of $S$ is $+4$. It can be oxidized to $SO_4^{2-}$ $(+6)$ and it can accept $H^+$ to form $HSO_3^-$.$4$. $SO_4^{2-}$ is the highest oxidation state of $S$ $(+6)$,so it cannot act as a reducing agent.$5$. $S_2O_4^{2-}$ (dithionite) is a strong reducing agent but is less commonly cited as a simple base compared to $SO_3^{2-}$.$6$. $HSO_4^-$ is acidic in nature.$7$. Therefore,$SO_3^{2-}$ is the correct answer.

Which of the following is both basic and a reducing agent?
