Question

copper can be electropleted over iron ring
(1) write equation showing oxidation and
reduction
(2) which metal is connected to the
Positive terminal of the cell​

Answer 1

Explanation:

Reduction: Fe3+(aq) + 3e– → Fe(s)

Oxidation: Mg(s) → Mg2+(aq) + 2e–

This pair of half-reactions can be balanced by ensuring that both have the same number of electrons. To do this, multiply the oxidation half-reaction by 3 and the reduction half-reaction by 2, so that each half-reaction has 6e–.

2 Fe3+(aq) + 6e– → 2 Fe(s)

3 Mg(s) → 3 Mg2+(aq) + 6e–

Adding these two half reactions together gives the balanced equation:

2 Fe3+(aq) + 3 Mg(s) → 2 Fe(s) + 3 Mg2+(aq)
