Why is the anode of a galvanic cell made with zinc and aluminum?

In a galvanic cell, the anode is typically made from a more reactive metal, which in this case is zinc. Zinc has a higher tendency to oxidize compared to aluminum, allowing it to release electrons more readily during the electrochemical reaction. This oxidation process generates electrical energy, making zinc an ideal choice for the anode. Although aluminum can also be used, zinc's reactivity ensures a more efficient and effective electron flow in the cell.
