To measure the amount of iron in a certain type of iron ore, an analytical chemist dissolves a 20.0 g sample in strong acid and titrates it to the endpoint with 40.5 mL of 0.2400 M potassium permanganate (KMnO) solution. The balanced chemical equation for the reaction is: 8H (ag) +5Fe2(aq)MnO (aq)5Fe (aq) + Mn (ag) + 4 H,O () 3+ 2 O precipitation What kind of reaction is this? acid-base X redox said this was a precipitation reaction, enter the chemical formula of the If you precipitate. If you said this was an acid-base reaction, enter the chemical formula of the reactant that is acting as the base. If said this was a redox reaction, enter the chemical symbol of the element you that is oxidized. Calculate the mass percent of Fe in the sample. Be sure your answer has 3 significant digits. 0% Explanation Check 2019 McGraw-Hill Education. All Rights Reserved. Terms of Use
