Many mining operations produce tailings that can be oxidized to form acids, including sulfuric acid. One chemical that reacts in this way is chalcopyrite, CuFeS2, whose net oxidation can be described by the following equation. 4 CUFES2(s) + 17 02(9) + 10 H2О() — 4 Fe (ОН), (8) + 4 CuSO, (aq) + 4 H-SO4 (aq) In a laboratory experiment to study weathering, a mining engineer put a 1.63 kg sample of CuFeS2 (s) near an empty 40 L container. Simulated weathering experiments were conducted and the runoff was collected, leading to 35.5 L of solution. A 25.00 mL aliquot of this solution was analyzed with 0.0100 M NaOH(aq). The titration required 31.3 mL of base. (a) What was the concentration (in M) of sulfuric acid? M (b) Assuming the only acid in the container comes from the reacted chalcopyrite, what mass (in g) of the chalcopyrite has reacted? (c) What percentage of the chalcopyrite reacted in this experiment?
