How many moles of `MnO_(4)^(-)` ions will react with 1 mole of ferrous oxalate in acid medium ?

A

`1//5`

B

`2//5`

C

`3//5`

D

`5//3`

Text Solution

Verified by Experts

The correct Answer is:
C
`2KMnO_(4)+3H_(2)SO_(4) to K_(2)SO_(4)+3H_(2)O+5[O]`
`2{:((COO^(-),),(|,Fe^(2+)),(COO^(-),)):}+3H_(2)SO_(4)+3[O]to Fe_(2)(SO_(4))_(3)+4CO_(2)+3H_(2)O`
`therefore 6 " mole" KMnO_(4)-= 10 " mole" FeC_(2)O_(4)`
`therefore 1 " mole" FeC_(2)O_(4)` will react with `(3)/(5)` mole of `KMnO_(4)`
