The anodic and cathodic behaviours of aluminium, iron, mercury steel (
HgSt), chrome-nickel steel (CrNiSt) and platinum have been studied in
a 2N NaCl electrolyte (pH = 5) by means of electrolysis. The potential
s of the cathodes and the theoretical and experimental discharge poten
tials of the systems have been determined. The cathodic and anodic ove
rpotentials produced on Al, Fe, HgSt, CrNiSt and Pt were predicted aga
inst a platinum anode and a platinum cathode, respectively. The amount
s of hydrogen gas produced at different times on the cathodes at a con
stant potential were measured and the hydrogen yield was calculated. F
rom the data obtained, it is suggested that Pt anode and Al or HgSt ca
thode, or Al anode and Pt cathode, couples should be employed for the
best electrolysis system.
