For the redox reaction,
`MnO_(4)^(-) + C_(2)O_(4)^(2-) + H^(+) rarr Mn^(2+) + CO_(2) + H_(2)O`
the correct coefficients of the reactants for the balanced reaction are

A

`{:(MnO _(4)^(-), C_(2)O_(4)^(2-), H^(+)), (2,5,16):}`

B

`{:(MnO _(4)^(-), C_(2)O_(4)^(2-), H^(+)), (6,5,2):}`

C

`{:(MnO _(4)^(-), C_(2)O_(4)^(2-), H^(+)), (5,16,2):}`

D

`{:(MnO _(4)^(-), C_(2)O_(4)^(2-), H^(+)), (2,16,5):}`

Text Solution

Verified by Experts

The correct Answer is:
A
`MnO_(4)^(-)+8H^(+)+5e^(-) to Mn^(2+)+4H_(2)O]xx2`
`{:(COOH),(|),(COOH):}to 2CO _(2)+ 2H^(+)+2e ^(-)]xx5`
`{:(" "COOH),(2MnO_(4)^(-)" "+5| +6h^(+) to),(" "COOH):}`
`2Mn^(2+) +10CO_(2)+8H_(2)O`
