Benzoic acid is an organic compound and insoluble in water. Mg(OH)2 is not
soluble in cold water. However, NA2SO4 in very soluble in water. So adding cold water in the
mixture first. the water phase containing NA2SO4 can be filtered out. The organic phase+ the
insoluble solid was isolated out into another container, where 3M HCl is then added. This will
convert Mg(OH)2 to soluble MgCl2 and water. adding more water to this mixture to extract. the
organic phase is benzoic acid, the water phase contains MgCl2, which can be converted back to
Mg(OH)2 by adding base.
