Definition of Selective discharge at the cathode
Check what you remember
Read the wording for your board, then hide it and explain Selective discharge at the cathode in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: AQA
At the negative electrode, the ion that gains electrons more readily is discharged, so either hydrogen or the metal is produced.
