Electrolysis

[Karla Baltierra Zamora 3C]

Hello, I was wondering if there are any specific equations that we would use with electrolysis? I'm just confused as to when it would be relevant in a problem. Thank you :)

Hi there! I am not 100% sure if there are any specific equations that we would use for electrolysis, but I could be totally wrong. However, I did find this one, Q=I⋅t.

Hi I don't think there are any specific equations per se that apply to electrolysis. The oxidation and reduction equations look the same as what we're familiar with, they're just not separated by a porous disc. I would just make sure you're familiar with the fact that...

- Electrolysis uses e- to drive non-spontaneous redox reactions, so it needs a constant external current to drive the rxn in the unfavorable direction and therefore the external voltage must be greater than the internal V
- It's a transfer of electrical energy to chemical energy
- The thing "pulling" the electrons and causing oxidation is the external current supply

and also be familiar with how electrolytic cells work specifically, hope this helps!
