\nIn the reaction ZnO + C \u2192 Zn + CO, zinc oxide (ZnO) loses oxygen to become zinc (Zn), undergoing reduction. Carbon (C) gains oxygen to become carbon monoxide (CO), undergoing oxidation.
\n<\/section>\n
\nA reducing agent is a substance that causes another substance to be reduced, while it itself is oxidized. In this reaction, carbon (C) removes oxygen from ZnO, thus causing the reduction of ZnO. Carbon itself is oxidized in the process. Therefore, carbon acts as a reducing agent.
\n<\/section>\n
\nConversely, an oxidising agent is a substance that causes another substance to be oxidized, while it itself is reduced. ZnO acts as the oxidising agent in this reaction because it provides oxygen for the oxidation of carbon and is itself reduced. This is a common method for the extraction of metals from their oxides using carbon as a reducing agent (smelting).
