WebThe copper metal is an electrode. The copper is undergoing oxidation; therefore, the copper electrode is the anode. The anode is connected to a voltmeter with a wire and the other terminal of the voltmeter is connected to a silver electrode by a wire. The silver is undergoing reduction; therefore, the silver electrode is the cathode. WebCalculate the potential for each cell as written at 25 ∘C. Indicate whether the metal electrode in the half‑reaction opposite the standard hydrogen electrode, S.H.E., would be the anode or the cathode if the cell was shorted and electrons were allowed to flow freely. markfacendi.caWebThus, cathode increases in mass as copper is deposited on it and the anode decreases in mass as copper from it dissolves.
