Question
Which the following statements about the given reaction are correct:3Fe(s) + 4H O (g) Fe O (s) + 4H (g) 2 2 3 2i) Iron metal is getting oxidizedii) Water is getting reducediii) Water is acting as reducing agentiv) Water is acting as oxidizine agenta) (i), (ii) and (iii) b) (iii) and (iv)c) (i), (ii) and (iv) d) (ii) and (iv)
Solution
The given reaction is: 3Fe(s) + 4H2O(g) -> Fe3O4(s) + 4H2(g)
Let's analyze each statement:
i) Iron metal is getting oxidized: This is correct. In the reaction, iron (Fe) is changing from an oxidation state of 0 in the reactants to an oxidation state of +8/3 in the product (Fe3O4). This increase in oxidation state indicates oxidation.
ii) Water is getting reduced: This is incorrect. In the reaction, the oxygen in water is changing from an oxidation state of -2 in the reactants to -2 in the product (Fe3O4), and the hydrogen is changing from an oxidation state of +1 in the reactants to 0 in the product (H2). The decrease in oxidation state for hydrogen indicates reduction, but it's the hydrogen that's getting reduced, not the water as a whole.
iii) Water is acting as reducing agent: This is incorrect. A reducing agent is a substance that reduces another substance by losing electrons (or in other words, it gets oxidized). In this reaction, it's the iron that's getting oxidized, not the water.
iv) Water is acting as oxidizing agent: This is correct. An oxidizing agent is a substance that oxidizes another substance by gaining electrons (or in other words, it gets reduced). In this reaction, the hydrogen in water is getting reduced, so water is acting as an oxidizing agent.
So, the correct answer is c) (i), (ii) and (iv).
