Question

Sketch the following galvanic cell. Identify the cathode and anode and show the direction of electron flow. Write the oxidation and the reduction half reaction.

Cu2+ (aq) + Mg (s) → Mg2+ (aq) + Cu (s)

Answer 1

The equation now reads: Cu2+ + Mg → Cu + Mg2+ This is called an ionic equation; it shows only the ions and atoms involved in the reaction.
