Question

In the given chemical reaction, which of the following chemical species acts as an oxidising agent and as a reducing agent, respectively? 2Al+Fe2O3Al2O3+2Fe2Al+Fe_2 O_3→Al_2 O_3+2Fe​​​

A.

Al and Fe

B.

Fe and Al

C.

Al2O3 and Fe\text{Al}_2\text{O}_3 \ \text{and} \ \text{Fe}​​

D.

Fe2O3 and Al\text{Fe}_2\text{O}_3 \ \text{and} \ \text{Al}

Correct option is D

Sol: The correct answer is (d) Fe2O3Fe_2O_3 and Al

Key points:

2Al+Fe2O3Al2O3+2Fe 2Al+Fe_2O_3→Al_2O_3+2Fe

The oxidizing agent is the species that gets reduced, meaning it gains electrons.

Fe2O3Fe_2O_3​ acts as the oxidizing agent because iron (Fe) in Fe2O3Fe_2O_3​ is reduced from an oxidation state of +3 in Fe2O3Fe_2O_3​ 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 inAl2O3Al_2O_3​​
