Flow of electrons
Is the flow of electrons always going to be form anode to cathode or are there circumstances where it's the other way around?

Re: Flow of electrons
Anode and cathode are defined that way...electrons go from anode to cathode...

Re: Flow of electrons
Electrons flow from the anode to cathode usually so I don't think there's an exception

Re: Flow of electrons
Electrons only flow from anode(-) to cathode(+), which makes sense since electrons have a negative charge so it will move towards the cathode to try to balance out the charge.

Re: Flow of electrons
Electrons always go from the anode to the cathode because oxidation, or removal of electron, is always and only happening at the anode.

Re: Flow of electrons
I think it is always from anode to cathode. Oxidation is loss of electrons at the anodes so then they flow to the cathode where there is the gain of electrons which is reduction

Re: Flow of electrons
Yes; anodes are oxidized and cathodes are reduced. Thus the flow of electrons is from oxidized substances to reduced substances.
Re: Flow of electrons
There are some confused answers here. The anode is not necessarily always negative — neither is the cathode always positive (exceptions are in non-spontaneous reactions). However, the anode is always oxidation and the cathode is always reduction, so then the electrons flow from anode to cathode.

Re: Flow of electrons
It always goes from the anode to the cathode in a Galvanic cell since the anode is negatively charged and the cathode is positively charged and will attract the electrons from the anode. However, in an electrolytic cell, the cathode and anode do not have the same charges, regardless the electron still flows from the anode to the cathode.
