`1` mole each of `FeC_(2)O_(4)` and `FeSO_(4)` is oxidised Calculate by `1M KMnO_(4)` in acidic medium. Calculate the volume ratio of `KMnO_(4)` used for `FeC_(2)O_(4)` and `FeSO_(4)`.

Answer

3

Explanation

`{:(Fe^(2+)+C_(2)O_(4)^(2-),rarrFe^(3+)+2CO_(2)^(4+)+3e,,,),( Fe^(2+)+SO_(4)^(2-),rarrFe^(3+)+SO_(4)^(2-)+e,,,),(Mn^(7+)+5e,rarrMn^(2+),,,):}`
Meq.of `FeC_(2)O_(4)="Meq.of" KMnO_(4)`
`1xx3xx1000=1xx5xxV_(1)`......(1)
Meq.of `FeSO_(4)="Meq.of"KMnO_(4)`
`1xx1xx1000=1xx5xxV_(2)`....(2)
By. eqs. (1) and (2),
`(V_(1))/(V_(2))=3`
