Question

Write the oxidation and reduction reactions for each redox reaction.

Fe(2+) + Co = Co(2+) + Fe
Oxidation:
Reduction:

Answer 1

Oxidation: Fe(2+) → Fe(3+).

Reduction: Co(3+) → Co(2+).

Step-by-step explanation:

In a redox reaction, one substance undergoes oxidation, while another substance undergoes reduction. In this case, we have the reaction Fe(2+) + Co → Co(2+) + Fe. To determine the oxidation and reduction reactions, we need to identify which substance gains or loses electrons.

Oxidation: The substance that gains oxygen or loses electrons is being oxidized. In this case, iron (Fe) is being oxidized from Fe(2+) to Fe(3+). This can be written as:

Fe(2+) → Fe(3+) + e-

Reduction: The substance that loses oxygen or gains electrons is being reduced. In this case, cobalt (Co) is being reduced from Co(3+) to Co(2+). This can be written as:

Co(3+) + e- → Co(2+)

Overall, the redox reaction can be written as the sum of the oxidation and reduction reactions:

Fe(2+) → Fe(3+) + e- (oxidation) + Co(3+) + e- → Co(2+) (reduction)

Fe(2+) + Co(3+) → Co(2+) + Fe(3+).
