A: Nickel electrodes used (partially) in H2SO4 experiment seen previous.
B: Burnt-out adapter used in the H2SO4 experiment. Somehow (not surprisingly) the current went way over its limit.
C: Sample of sulphuric acid, coloured red for ID. The colour turned clear after two minutes of operation.
D: Carbon black electrodes tested in H2SO4, where the anode disintegrated into powdered carbon, or a form of hydrocarbon thereof. Cathode collected some sort of brown film.
E: Copper wire electrodes tested in same solution as carbon. As expected, the anode turned into copper sulphate.
F: Assorted electrode metals that were later used for more tests in different solutions, including Ammonium nitrate. What a disaster that was!
