. Consider the oxidation—reduction reaction

Mg ( s ) + Cu 2 + ( aq ) Mg 2 + ( a q ) + Cu ( s )    Sketch a galvanic cell that uses this reaction. Which metal ion is reduced? Which metal is oxidized? What half-reaction takes place at the anode in the cell? What half-reaction takes place at the cathode?

Interpretation Introduction

Interpretation:

A galvanic cell that uses the given reaction should be sketched. Which metal is reduced and which metal is oxidized should be identified. Half cell reactions should be written.

Concept Introduction:

A Galvanic cell also known as electrochemical battery is a device that exploits a spontaneous oxidation reduction reaction to produce electrical energy. Here oxidizing agent and reducing agent has been separated, so that the electron generated by oxidation should travel through a wire from reducing agent to oxidizing agent.

Explanation

According to the reaction Mg has been oxidized into Mg2 + and Cu2 + has been reduced into Cu.

Anode Half cell reaction: where the oxidation occurs

Mg(s)Mg(aq)2+
