3F→Eijidate: 可是如果我把正極換成活性比較大的金屬,是否有可能改和04/05 10:43
4F→Eijidate: 負極燒杯的硫酸鋅反應,所以負極就變成原本正極這一杯?04/05 10:44
5F→Eijidate: 在比的是"負極金屬與正極燒杯液體"和"正極金屬與負極燒04/05 10:45
6F→Eijidate: 杯液體"之間的氧化還原電位?哪個比較強就哪邊變負極?04/05 10:46
8F→Eijidate: 那請問如果正負極都泡在同一杯溶液裡呢?04/05 13:55
9F→Eijidate: 為什麼有聽過人說鋅和銅都泡在硫酸銅裡,還原還是在銅上?04/05 13:56
10F→Eijidate: 感覺這時候銅離子直接找負極的鋅交換電子就好了啊?04/05 14:44
11F→Eijidate: 為什麼還要捨近求遠去找銅片要電子?04/05 14:44
