electroliyis decomposition of Aluminum
Answers
Answer:
Decomposition reactions are those in which one compound breaks down (or decomposes) to form two or more products.
There are many compounds that will decompose if exposed to some stress. The stress that sets off these reactions may be in the form of heat, pressure, electricity, or shock.
Large amounts of aluminum are produced from the decompostion of aluminum oxide. This is done by applying heat and electricity to solutions of aluminum oxide:

Explanation:
Electrolysis of the alumina/cryolite solution gives aluminium at the cathode and oxygen at the anode. Aluminium is more dense than the alumina/cryolite solution, and so falls to the bottom of the cell where it can be tapped off as pure liquid metal. Oxygen is discharged at the positive carbon (graphite) anode.
