The following is an extract from 'Metals in the Service of Man, Alexander and Street/Pelican 1976. 'Alumina (aluminium oxide) has a very high melting point of over 2000^@ C so that it cannot readily be liquefied. However, conversion of alumina to aluminium and oxygen, by electrolysis, can occur when it is dissolved in some other substance : The aluminium oxide for the electrolytic extraction of aluminium is obtained by heating aluminium hydroxide. Write the equation for this reaction.
