A lead-acid battery that is used in cars and trucks is powered by the reaction: PbO₂(s) + Pb(s) + 2H₂SO₄(aq)$\rightarrow$2PbSO₄(s) + H₂O(l) The substance that is reduced in this battery is:

Question

Quizplus · Accepted Answer

In a redox reaction, the substance that is oxidized loses electrons and the substance that is reduced gains electrons. In the given reaction, PbO and Pb are both oxidized to form PbSO4, while H2SO4 is reduced to form H2O. Therefore, the substance that is reduced in this battery is H2SO4, which corresponds to choice C.
