To measure the amount of iron in a certain type of iron ore, an analytical chemist dissolves a sample in strong acid and titrates it to the endpoint with of potassium permanganate solution. The balanced chemical equation for the reaction is: 8H' (aq) + 5Fe2 (aq) + MnO4 (aq) SFe3 (aq) + Mn2 (aq) +4H2O precipitatio. What kind of reaction is this?
A. If you said this was a precipitation reaction, enter the chemical formula of the precipitate.
B. If you said this was an acid-base reaction, enter the chemical formula of the reactant that is acting as the base.
C. If you said this was a redox reaction, enter the chemical symbol of the element that is oxidized.
