1 mol of ferric oxalate is oxidised by xmol of {MnO_4}^- in . . . - Toppr In acidic medium, two moles of permanganate oxidizes 5 moles of oxalic acid Also, 1 mole of permanganate oxidizes 5 moles of Fe (II) ions 1 mole of ferrous oxalate gives 1 mole of Fe (II) ions and 1 mole of oxalate ions It will require 1 5 moles of permanganate for the oxidation of Fe (II) ions and 2 5 moles of permanganate for the oxidation of oxalate ions Total permanganate required is 1
