Aluminum is one of the most versatile metals it is formed, Ask an Expert

Academics

Aluminum is one of the most versatile metals. It is formed by the Hall-Heroult process in which molten cryolite, Na3AlF6, is utilized as a solvent for the aluminum ore. Cryolite undergoes extremely slight decomposition with heat to produce a tiny amount of F2, which escapes into the atmosphere above the solvent. Kc is 2 10-104 at 1300 K for the reaction. Na3AlF6(l) 3 Na(l) + Al(l) + 3 F2(g) Define what is the concentration of F2 over a bath of molten cryolite at this temperature? 8 1017 M 3 10-35 M 6 10-74 M 8 10-312 M 5 10102 M
