Which of the following statements about the given reaction are correct? 3Fe (s) + 4H2O (g) → Fe3O4 (s) + 4 H2 (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), (zi) and (iii) (b) (in) and (iv) (c) (i), (ii) and (iv) (d) (ii) and (iv)
Answer: (c) (i), (ii) and (iv) Here, oxygen combines with water to get oxidized. Oxygen is removed from water hence, it is getting reduced. Water is providing oxygen and it acts as an oxidizing agent. On introducing two molecules to each other, one molecule loses an electron. This reaction is called oxidation. On introducing two molecules to each other, one molecule gains an electron. This reaction is called reduction. The oxidized substance is called a reduction agent. The reduced substance is called an oxidizing agent.
