2) Under acidic conditions, an aqueous solution of permanganate ion is often used to oxidize an aqueous solution of Iron II to an aqueous solution of Iron III ion. In addition, the permanganate ion is reduced to an aqueous solution of the Manganese II ion. A 50.00 mL sample of solution containing the Iron II ions is titrated with 20.62 mL of a 0.0216 M potassium permanganate solution to oxidize all the Iron II ions. What was the concentration of Iron II ions in the original 50.00 mL sample?
