Raw aluminium readily forms a tough oxide layer when exposed to air, which protects the metal from further corrosion or reactions with many chemicals. This oxide layer can form incredibly quickly ...

Sodium aluminate forms through the chemical reaction of aluminum oxide with sodium hydroxide and water, as follows: The residues sink gradually to the bottom of the tank and are later removed. In the ...

Aluminium is more reactive than carbon so it must be extracted from its compounds using electrolysis. Even though aluminium is more abundant than iron in the Earth's crust, aluminium is more ...
