Question

2.
The percentage of iron II) ions, fe?' in a vitamiin tablet can be estimated by dissolving the
tablet in dilute sulfuric acid and titrating with standard potassium manganate(VII) solution,
KMnO,aq). During the process iron(II) is oxidized to iron(III) and the manganate(VII) ion is
reduced to the manganese(II ion. Mn" (aq). It was found that one tablet with a mass of 113 z
requured 116 cm' of 2.00 x 10-2 mol dm' KMnO,aq) to reach the end-point.
Calculate the amount. in moles. of Mno, ions present in 11.6 cm of
2.00 x 10² mol dm-KMnO, (aq).
