我想問點解ECS唔可以應用係chem.cell 內既
eg.有個chem.cell
左邊係Mg浸在MgNo3 sol.
右邊係Zn浸在ZnNo3 sol.
complete左個circuit同有suitable既salt bridge
咁d e- 應該由mg走到zn in the external circuit.
咁係
anode: Mg --->Mg2+ + 2e- (呢個我明)
cathode:Zn2+ + 2e- --->Zn / 2H+ +2e- ---> H2??
如果係Zn果個既話, 點解呢?
根據ECS, H+係係Zn2+之下,所以有更高既tendency去gain e-.((係conc. effect?))
