Question
In a zinc-copper cell, Zn | Zn(1M) || Cu(1M) | Cu, which electrode is negative?Group of answer choicesCu(s)Zn(s)Zn(aq)Cu(aq)
Solution
In a zinc-copper cell, the zinc electrode is the negative one. This is because in this type of cell, zinc is the anode where oxidation occurs. During this process, zinc loses electrons and becomes positively charged, making the zinc electrode negative. So, the correct answer is Zn(s).
