The number of mole of oxalate ions oxidised by one mole of `MnO_(4)^(-)` ion is:

A

`1//5`

B

`2//5`

C

`5//2`

D

`5`

Text Solution

Verified by Experts

The correct Answer is:
C
The balanced equation is
`5C_(2)O_(4)^(2-)+26H^(+)+2MnO_(4)^(-) rarr 5CO_(2)+18H_(2)O+2Mn^(2+)`
Now `2` moles of `MnO_(4)^(-)` requires `C_(2)O_(4)^(-2)=5` mol
`:. 1` mole of `MnO_(4)^(-) rarr (5)/(2)` mol
