No, I wrote for the evidence part 'if the electrode is clean then naoh was there' because i couldn't think of anything at that time...But to produce NaOH, electrolysis of brine occurs, not water? Cl- is oxidised and water is reduced.
OH- seems okay to me as well, but who knows what's up with the marking criteria.
Was there a question asking for the uses of NaOH? Great. Lol.
