Q.
For the redox reaction,

${MnO}_{4}^{-} + C_{2} O_{4}^{2 -} + H^{+} ⟶ {Mn}^{2 +} + {CO}_{2} + H_{2} O$

The correct coefficients of the reactants for the balanced equation are: [2018]

Solution

Q.
For the redox reaction,

${MnO}_{4}^{-} + C_{2} O_{4}^{2 -} + H^{+} ⟶ {Mn}^{2 +} + {CO}_{2} + H_{2} O$

The correct coefficients of the reactants for the balanced equation are: [2018]

1 ${MnO}_{4}^{-} - 16,$ $C_{2} O_{4}^{2 -} - 5,$ $H^{+} - 2$

2 ${MnO}_{4}^{-} - 2,$ $C_{2} O_{4}^{2 -} - 5,$ $H^{+} - 16$

3 ${MnO}_{4}^{-} - 2,$ $C_{2} O_{4}^{2 -} - 16,$ $H^{+} - 5$

4 ${MnO}_{4}^{-} - 5,$ $C_{2} O_{4}^{2 -} - 16,$ $H^{+} - 2$

Ans.
(2)

The correct balanced equation is

$2 {MnO}_{4}^{-} + 5 C_{2} O_{4}^{2 -} + 16 H^{+} \to 2 {Mn}^{2 +} + 10 {CO}_{2} + 8 H_{2} O$
