Flow of electrons

Postby Noe BM 1J » Sun Feb 23, 2020 5:59 pm

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

Anode and cathode are defined that way...electrons go from anode to cathode...

Electrons flow from the anode to cathode usually so I don't think there's an exception

I'm pretty sure that it is always anode to cathode.

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.

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

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

Yes; anodes are oxidized and cathodes are reduced. Thus the flow of electrons is from oxidized substances to reduced substances.

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.

Anode to cathode

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.

Electrons will always go in the direction of the anode to the cathode
