The number of mole of `KMnO_(4)` that will be needed to react completely with one mole of ferrous oxalate in acidic solution is:

Options

A. `3//5`
B. `2//5`
C. `4//5`
D. `1`

Answer

A

Explanation

`{:(Mn^(7+),+5e,rarr,Mn^(2+),),(,Fe^(2+),rarr,Fe^(3+),+e),(,(C^(3+))_(2),rarr,2C^(4+),+2e):}`
`:. 3` mole of `KMnO_(4) -= 5` mole of `FeC_(2)O_(4)`
