Identify the Anode in a Galvanic Cell

In electrochemistry, we often study the relationship between chemical reactions and electrical energy. One of the most commonly discussed concepts is that of an electrochemical cell, which can either be a galvanic (voltaic) cell or an electrolytic cell. A galvanic cell generates electrical energy from spontaneous chemical reactions, while an electrolytic cell uses electrical energy to drive a non-spontaneous reaction.

Consider a galvanic cell composed of a copper electrode submerged in a copper(II) sulfate solution and a zinc electrode submerged in a zinc sulfate solution. The standard electrode potentials ( E° ) for these half-reactions are as follows:

Cu²⁺ + 2e^- → Cu(s)    E° = +0.34 V
Zinc ion reduction: Zn²⁺ + 2e^- → Zn(s)    E° = -0.76 V

Based on this information, which electrode acts as the anode in this galvanic cell?
