The number of mole of oxalate ions oxidized by one mole of

\mathrm{MnO}_4^ -

ion is:

View answer and explanation

Correct option: C

\frac{5}{2}

Option C (

\frac{5}{2}

) is correct because each permanganate ion gains 5 electrons, while each oxalate ion loses 2 electrons, requiring a ratio of 2 permanganate ions to 5 oxalate ions.
