For the redox reaction MnO(4)^(ө)+C(2)...

For the redox reaction
`MnO_(4)^(ө)+C_(2)O_(4)^(2-)+H^(o+)rarrMn^(2+)+CO_(2)+H_(2)O`
the correct coefficients of the reactions for the balanced reaction are

A

(`1MnO_(4)^(-)=16`, `C_(2)O_(4)^(2-)=5`, `H^(+)=2`)

B

(`1MnO_(4)^(-)=2`, `C_(2)O_(4)^(2-)=5`, `H^(+)=16`)

C

(`1MnO_(4)^(-)=2`, `C_(2)O_(4)^(2-)=16`, `H^(+)=5`)

D

(`1MnO_(4)^(-)=5`, `C_(2)O_(4)^(2-)=16`, `H^(+)=2`)

Text Solution

Verified by Experts

The correct Answer is:
B
`MnO_(4)^(-)+5e^(-) rarr Mn^(2+)` ...(`1`)

multiplying (`1`) by `2` and (`2`) by `5` to balance `e^(-)`
`^(2)MnO_(4)^(-)+5C_(2)O_(4)^(-2) rarr 2Mn^(+2+10 CO_(2))`
Only suitable choice is (`b`).
