A wide range of electrolytes can be used.. Sodium phosphate,
carbonate, bicarbonate, ammonium sulfate, etc. In the US,
bicarbonate of soda was most frequently employed by amateurs because
it was cheap and easy to obtain.
The same apparently applies to the anode--aluminum is not the only
metal that exhibits the property.
