Which of the following statements about the given reaction are correct?
3Fe(s) + 4H 2 O(g) → Fe 3 O 4 (s) + 4H 2 (g)
(i) Iron metal is getting oxidised (ii) Water is getting reduced
(iii) Water is acting as reducing agent (iv) Water is acting as oxidising agent
(A) (i), (ii) and (iii)
(B) (iii) and (iv)
(C) (i), (ii) and (iv)
(D) (ii) and (iv)
- Addition of oxygen is known as oxidation
- Removal of oxygen is known as reduction.
Since in the equation
- Oxygen is being removed from Water (H 2 O)
- and is added to Fe.
Therefore, Fe is undergoing oxidation and H 2 O reduction.
- The substance which oxidises the other substances in a chemical reaction is known as an oxidising agent.
- Likewise, the substance which reduces the other substance in a chemical reaction is known as a reducing agent.
Here, Water acts as reducing agent
So, the correct option is (c) (i), (ii) and (iv)
