In the following chemical reaction, which substance is the oxidizing agent and which is the reducing agent?PbO(s) + C(s) → Pb(s) + CO(g)oxidizing agent: C CO Pb PbOreducing agent: C CO Pb PbO
Question
In the following chemical reaction, which substance is the oxidizing agent and which is the reducing agent?PbO(s) + C(s) → Pb(s) + CO(g)oxidizing agent: C CO Pb PbOreducing agent: C CO Pb PbO
Solution
In a redox reaction, the substance that is reduced is the oxidizing agent and the substance that is oxidized is the reducing agent.
In the given reaction: PbO(s) + C(s) → Pb(s) + CO(g)
-
PbO is reduced to Pb because it gains electrons (the oxidation state of Pb decreases from +2 in PbO to 0 in Pb). Therefore, PbO is the oxidizing agent.
-
C is oxidized to CO because it loses electrons (the oxidation state of C increases from 0 in C to +2 in CO). Therefore, C is the reducing agent.
