_____________________________________________________________________________________________________
Observation
Many candidates correctly mentioned gold rod/plate and iron spoon for the anode and cathode respectively; but failed to mention "solution/molten gold salt' as the electrolyte. Performance was above average. The expected answers are: (a) Gold rod/plate; (b) Iron spoon; (c) Solution/molten gold salt.
