In the extraction of aluminium : -
Which soln. is used to react with bauxite as a first in obtaining pure aluminium oxide.

Answer the following question related with the isolation of aluminium from bauxite: Which solution is used to react with bauxite as a first step in obtaining pure aluminium oxide?

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 : Which solution is used to react with bauxite as a first step in obtaining pure aluminium oxide ?

(i)Name the solution used to react with Bauxite as a first step in obtaining pure aluminium oxide, in the Baeyer's process. (ii) Write the equation for the reaction where the aluminum oxide for the electrolytic extraction of aluminum is obtained by heating aluminium hydroxide.
