Cell Diagram with one reactant

Postby Alex Tchekanov Dis 2k » Sun Feb 23, 2020 3:11 pm

For problem 6L7 part A: AgBr(s) = Ag+(aq) + Br-(aq)
For questions like these when you only have one reactant and it is a solid, how do you know how to break it down in the anode and cathode half-reactions? Is it problem by problem-based or is there a set of rules that you can follow to know how to do this?

I think it depends on when you break the equations down, is there a clear one that has something being reduced and a clear one that has something being oxidized. Then you can decide which is the anode and which is the cathode.
