An ore was found to contain iron and ferric oxide, if 0.5g of the ore, after solution in acid and complete reduction of the iron, requires 25.50ml of potassium permanganate (1ml = 0.01260g H₂C2O4.2H₂O) for oxidation? What is the percentage of iron and ferric oxide? What volume of this potassium permanganate would be required for a 10.0g sample of 3.00% (by wt.) H₂O2 solution (5H₂O2 + 2MnO4 + 6H+ → 2Mn+² +502 + 8H₂O)
