I am placing my question here as it is electrochemistry
Volta, in his pile, generated voltage and at least a few mA of current
He had 100 copper disks separated from zinc disks by wet blotting-paper
So each gave 1.2 volts and he had lots of volts.
But THINK about this!
ALL surfaces are coated by a monolayer of water!
Especially in UK where I live!
So his battery was cu water zn water cu water zn ...
Total 1.2 -1.2+1.2-1.2 +1.2... = 0 volts.
So how THICK does an electrolyte have to be to be an electrolyte?
And WHY is copper/zinc 1.2 to 1.4 volts and lead/lead peroxide 2 to 2.7 volts
How is it related to the electron fermi levels
Why are the best anodes (like PbO2) semiconductors?
Why is Zn/C 1.4 volts in NH4Cl with MnO2 "depolariser" and
Zn/C in the dichromate cell and Grove cell 2.0 volts.
Why don't they include non-metals in the "Electrochemical Series"?
