Hi passionated Scientists:Perhaps you have used a redox reaction in the laboratory to analize some sustance, so I wanna ask youCan you explain me whats "potential" in an electrochemical cell? what is its meaning?what´s the meaning of ΔΕ? I know it could be a diffcult theme, but, would you help me?
That's a chemist's answer. I'm surprised at you lightarrow.
There are several 'open' statements in your answer that you could help me with.How do you get hold of a Hydrogen Electrode?
What input resistance can your voltmeter have before your measurement goes wrong?
(The first is a genuine question.)
What is potential at a point? It's the energy needed to bring one coulomb of charge to that point. The Potential difference between two points is the energy needed to bring one coulomb of charge from one point to the other. (Energy may be put in or taken out, depending on the sign of the charge / direction of the field, so the potential may be + or -).Is that answer any use to a Chemist?There seem to be a huge leap between connecting wires up to an electric circuit and measuring chemical potentials.
