Equations showing oxidation/reduction at each electrode
Cathode
Anode
Al3++3e−→Al(l)Al^{3+} + 3e^- \rightarrow Al(l)Al3++3e−→Al(l)
Gain electrons to form Al metal
2O2−→O2(g)+4e−2O^{2-} \rightarrow O_2(g) + 4e^-2O2−→O2(g)+4e−
Lose electrons to form O2O_2O2 gas
Three electrons (3e−3e^-3e−)
Ions gain electrons
Ions lose electrons
Charges on both sides
Metal extraction, electroplating, chemical production
