- Voltaic cell behavior with no external connection
Hi,
googling for Voltaic cell I found this video about it. At minute 2:35 to 2:54 you can see that, without any electrical conductor connected between electrodes, in the Copper half-cell the metal electrode (Cathode) gets an amount of negative charges (electrons). Basically what described there is that Copper atoms oxidize passing in solution as Cu++ cations loosing electrons inside the Copper electrode.
As far as I Know actually, at least when an external connection is in place, the opposite reaction (Copper ions reduction) should take place at the Cathode electrode.
Do you think that video is correct ? Thanks.
