Hello,
I did an electrolysis practical where copper sulfate was electrolysed using copper electrodes.

One question I did asked to calculate the cell efficiency for each electrode (cathode and anode). I have calculated this using the equation actual amount/theoretical amount * 100.
But there is a question I dont understand - "what should have been the true efficiency of the anode and cathode of the same cell?" How can I calculate this??

It would be great if you could help,
Thank you,
Tegan

theoretically, all the copper(II) and sulphate ions in solution will be discharged during the process. this is your theoretical amount
