In the extraction of Al, impure Al2O3 is dissolved in conc. NaOH to form sodium aluminate and leaving impurities behind. What is the name of this process?
In the extraction of aluminium, impure Al2O3 is dissolved in concentrated NaOH to form NaAlO2. This method is known as leaching of alumina.
Al2O3(s) + 2 NaOH(aq) + 3 H2O(l) → 2 Na[Al(OH)4](aq)
