Answer:
Iron is being oxidised.
Step-by-step explanation:
To determine the right answer to the question, it is important that we write the half reaction.
The equation for the half reaction is given below:
Fe —> Fe^2+ + 2e^-
Next, we shall determine the change in the oxidation number of iron, Fe. This is illustrated below:
Fe = 0
Fe = +2
From the above, we can see that the oxidation number of iron, Fe changes from 0 to +2 i.e the oxidation number of iron, Fe increased.
This indicates that iron, Fe is being oxidised.
