Chromium: isolation. Isolation: it is not normally necessary to make chromium in the laboratory as it is so readily available commercially.The most useful source of chromium commercially is the ore chromite, FeCr 2 O 4.Oxidation of this ore by air in molten alkali gives sodium chromate, Na 2 CrO 4 in which the chromium is in the +6 oxidation state. This is converted to the Cr(III) oxide Cr 2 O ...
