Concept:The zinc electrode in a galvanic cell is the anode, where oxidation occurs.
Explanation:Zinc atoms lose electrons to form zinc ions:
Zn→Zn2++2e−This loss of electrons is oxidation.
The released electrons flow through the external circuit to the copper electrode.
Therefore, the zinc electrode is the source of electrons in the cell.
It does not undergo reduction, it is the negative electrode, and it produces rather than uses up electrons.
Answer:C. production of electrons.
