In a simple cell made from zinc and copper in dilute sulfuric acid, which is the negative electrode?
Answer and explanation
Correct answer: D. Zinc
Zinc is more reactive, so it loses electrons more readily and forms the negative pole.
Answer: Zinc.
Why not the others: Copper: copper is less reactive and forms the positive electrode. Both electrodes: one electrode is positive and the other negative. Sulfuric acid: it is the electrolyte.
