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: 3 + 2+ 5Fe (aq) + Mn (aq) + 4 H,0 () 8H (aq) + 5Fe(aq) + MnO, (aq) precipitation acid-base What kind of reaction is this? ? redox 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. said this was a redox reaction, enter the chemical symbol of the element If you that is oxidized.
