Redox Reactions And Electrochemistry Ques 352

Question: For the redox reaction $M n {O^{-}}_{4}$ $+$ $C_{2} O_{4}^{2 -}$ $+$ $H^{+}$ $\to M N^{2 +}$ $+ C O_{2}$ $+ H_{2} O$ the correct coefficients of the reactants for the balanced reaction are

Options:

A) $M n O_{4}^{-}$ $C_{2} O_{4}^{2 -}$ $H^{+}$ 2 5 16

B) $M n O_{4}^{-}$ $C_{2} O_{4}^{2 -}$ $H^{+}$ 16 5 2

C) $M n O_{4}^{-}$ $C_{2} O_{4}^{2 -}$ $H^{+}$ 5 16 2

D) $M n O_{4}^{-}$ $C_{2} O_{4}^{2 -}$ $H^{+}$ 2 16 5

Show Answer

Answer:

Correct Answer: A

Solution:

[a] The balance equation is $2 M n O_{4}^{2 -} + 5 C_{2} O_{4}^{2 -} + 16 H^{+} \to 2 M n^{2 +} + 10 C O_{2} + 8 H_{2} O$
