Voltage and standard reduction potential?

Click For Summary
SUMMARY

This discussion centers on the relationship between voltage, electron movement, and standard reduction potential in electrochemistry. Voltage is defined as the work done per unit charge, with electrons moving from areas of high potential to low potential. The anode, typically associated with oxidation, does not necessarily have a higher standard reduction potential (Eo) than the cathode, which is where reduction occurs. Clarifying these concepts is essential for understanding electrochemical cells and their functioning.

PREREQUISITES
  • Understanding of basic electrochemistry principles

We're doing electrochemistry this week and this concept confuses greatly. I know that voltage is the work per unit charge. And electrons move from high potential(is this voltage as well?) to low potential- what is meant by this by the way? How is this related to standard reduction potential? If electrons move from the anode(which I would assume is high potential), should it not have a higher potential(Eo) than the cathode? I know I'm mixing up a lot of concepts here but can anyone clear it up? Thank you.

I suggest you ask the electron and potential part in the physics forum (if I move the thread there, we risk it will be bounced back :wink:). Once you get this part ready, we can get back to the standard reduction potential.
