Write the two half-reactions that occur in this electroplating process. Be sure to include the states of the elements or ions.

Answer:

Answer 1

The electroplating process of the coin results in the coating of the coin with copper metal.

What is electroplating?

Electroplating is the process of using coating the surface of a metal with another one electrolytic cell.

The electroplating of the coin is done using copper as the anode and the coin as the cathode. The electrolyte is copper sulfate solution.

Oxidation occurs at the anode with the copper metal being converted to copper (ii) ions.

Reduction occurred at the cathode as the copper (ii) ions in the solution accept electrons to become copper metal and the coin being coated with copper.

The half-reactions are shown below:

At the anode:

$Cu(s) \rightarrow Cu^{2+}(aq) + 2e^{-}$

At the cathode:

$Cu^{2+}(aq) + 2e{-} \rightarrow Cu(s)$

Therefore, the electroplating process of the coin results in the coating of the coin with copper metal.
