I think most teaching material for cyclic voltammetry is often entirely theoretical and so I have created some material that theoretical and practical. Please let me know what you think and what else would be useful for teaching electro-analytical/electrochemistry - https://www.zimmerpeacock.com/2025/05/03/theoretical-and-practical-introduction-to-cyclic-voltammetry
Potassium ferricyanide is (K3[Fe(CN)6]), iron is in oxidation state +3. You start recording the CV at -200 mV and reduce Fe(III) to Fe(II) and then "The forward scan oxidizes ferrocyanide." This is absolutely wrong setting. You are supposed to start from 600 mV.
Full stop and no more comments.
Good point it will make for a more elegant looking CV, it's a carry over from when I used to make the solutions 50:50 ferri/ferro. I will do that. Best regards Martin Peacock
