In the given chemical reaction, which of the following chemical species acts as an oxidising agent and as a reducing agent, respectively?
Sol: The correct answer is (d) and Al
Key points:
The oxidizing agent is the species that gets reduced, meaning it gains electrons.
acts as the oxidizing agent because iron (Fe) in is reduced from an oxidation state of +3 in to 0 in Fe.
The reducing agent is the species that gets oxidized, meaning it loses electrons.
Al acts as the reducing agent because aluminum (Al) is oxidized from an oxidation state of 0 in Al to +3 in
