An oxidant (oxidizing agent) is a substance that accepts electrons and is itself reduced. A reductant (reducing agent) is a substance that donates electrons and is itself oxidized. In this reaction, Cu(I) gains electrons to become Cu(0), hence Cu(I) is the oxidant. S(-2) loses electrons to become S(+4), hence S(-2) is the reductant.
Consider the following redox reaction: 2Cu2O (s) + Cu2S (s) —— 6Cu (s) + SO2 (g) Identify the species among the following acting as oxidant and reductant, respectively:
