Question

Identify the reducing agent: Fe2O3 + 3CO -------- 2Fe + 3CO2. Also explain it.

Answer 1

A reducing agent refers to that compound or element which loses electrons. What it basically means that it is oxidized.

In the following reaction we see that 3CO starts to gain oxygen while it is reacting with Fe2O3 and hence become 3CO2.

Since, 3CO is getting oxidized, hence, the reducing agent is 3CO.
