Title: Are there liquid electrodes?
Post by: scientizscht on 06/08/2020 13:52:47
Hello

When a molecule gets oxidised and loses an electron, is it possible for this electron to move in the solution and go to another molecule that will get reduced? Is it possible this move of electrons that will take place without an electrode?

If yes, how exactly? And is there a chance the electron gets lost in the wider solution and not be transferred to the reductant?

Are there liquid electrodes?
Yes, mercury is the classic example, Galium sometimes gets used too.
The most common - in terms of tonnage is the aluminium in the electrolytic cells used for making the metal from the oxide.

Did you not realise that this has nothing to do with the question you asked in the title?

A new kind of battery stores energy in what researchers are calling “rechargeable fuel”—electrodes in liquid form. The result can be either recharged like a conventional battery or replaced by pumping in new fuel like gasoline.

For The above question, The answer is yes.
There are electrodes.
