Q. For redox reaction, ${MnO}_{4}^{-} + C_{2}O_{4}^{2 -} + H^{+} \longrightarrow {Mn}^{2 +} + {CO}_{2} + H_{2}O$ coefficient of reactants in balanced states are ${MnO}_{4}^{-}$ ${C_{2}O}_{4}^{2 -}$ $H^{+}$
A) 2 5 16
B) 16 5 2
C) 5 16 2
D) 2 16 5
Explanation
(a)
Following is balanced redox reaction.
${2MnO}_{4}^{-} + 5C_{2}O_{4}^{2 -} + 16H^{+} \longrightarrow 2{Mn}^{2 +} + 10{CO}_{2} + 8H_{2}O$
So, coefficients of ${MnO}_{4}^{-},C_{2}O_{4}^{2 -}\ and\ H^{+}are\ 2,5,and\ 16\ respectively.$
