Understanding Galvanic Cells

Easy General Chemistry Electrochemistry

During a laboratory experiment, a student observes the electrochemical reaction occurring in a galvanic cell. The cell is constructed with a zinc electrode (anode) and a copper electrode (cathode) submerged in their respective sulfate solutions. The zinc electrode is undergoing oxidation while the copper electrode is undergoing reduction.

Which of the following statements accurately describes the galvanic cell under these conditions?

The zinc electrode gains mass due to the reduction of zinc ions.

The copper electrode loses mass due to the oxidation of copper ions.

Electrons flow from the copper electrode to the zinc electrode.

The cell generates electrical energy through spontaneous redox reactions.
