Question

Match the reactions in Column I with nature of the reactions/type of the products in Column II.

Answer 1

(a) $O_2^{-}\to O_2+O_2^{2-}$
(b) $Cr{O}_4^{2-}+H^{+}\to {Cr}_2{O}_7^{2-}$
(c) $Mn{O}_4^{-}+{NO}_2^{-}+H^{+}\to {Mn}^{2+}+{NO}_3^{-}$
(d) ${NO}_3^{-}+H_2{SO}_4+{Fe}^{2+}\to {Fe}_2{\left({SO}_3\right)}_3+NO$
