To measure the amount of iron in a certain type of iron ore an analytical chemist dissolves a 21 00 g sample in strong acid and titrates it to the endpoint with 29 3 mL of 0 4800M potassium permanganate KMnO4 solution The balanced chemical equation for the reaction is 8H aq 5Fe aq MnO4 aq What kind of reaction is this 1 3 2 SFe aq Mn aq 4H 0 1 If you said this was a precipitation reaction enter the chemical formula of the precipitate If you said this was an acid base reaction enter the chemical formula of the reactant that is acting as the base If you said this was a redox reaction enter the chemical symbol of the element that is oxidized Calculate the mass percent of Fe in the sample Be sure your answer has 3 significant digits precipitation acid base redox 0 0 0 X 5 1x30
