The extraction of aluminium and sodium by electrolysis
How do we extract reactive metals that cannot be obtained using carbon? Why do we need to use electrolysis to obtain certain metals from their ores? e.g. how do we extract aluminium from its bauxite ore containing aluminium oxide? How do we extract sodium from salts like sodium chloride? All the electrolytic process are described complete with the electrolysis electrode equations. Scroll down for revision notes on extraction procedures and theory which should prove useful for school/college assignments/projects on ways of extracting metals from their ores.
