`3Fe(s) + 4H_(2)O(g) to Fe_(3)O_(4)(s) + 4H_(2)(g)`
1. Iron is getting oxidised.
2. Water is getting reduced.
3. Water is acting as reducing agent.
4. Water is acting as oxidising agent.

A

1,2 and 3

B

3 and 4

C

1,2 and 4

D

2 and 3

Text Solution

Verified by Experts

The correct Answer is:
C

The increases in oxidation state of an atom, through a chemical reaction, is known as an oxidation, The oxidation number of Fe increases from zero to 8/3. Iron acts as a reducting agent , a decreases in oxidation state is known as a reduction. The oxidation number of hydrogen is decreases from + 1 to zero. Water acts as a oxidizing agent.
