1. (a) Alumina melts at 2045 oC. The molten solution of alumina in cryolite melts at about 950 oC so much less energy is needed to obtain liquid aluminum(III) ions.(b) Cathode (−) : Al3+(l) + 3e− → Al(l)Anode (+) : 2O2−(l) → O2(g) + 4 e−(c) Some of the oxygen gas released reacts with the graphite anode to form carbon dioxide.C(s) + O2(g) → CO2(g)(d) The carbon dioxide released from the anode is a greenhouse...
