Iron(III) oxide is a product of the oxidation of iron. It can be prepared in the laboratory by electrolyzing a solution of sodium bicarbonate, an inert electrolyte, with an iron anode: 4 fe + 3 o 2 + 2 h 2 o â 4 feo(oh)
you obtain iron hydroxide and sodium sulphate fe2so3 naoh fe oh 2 na2so3 as you can see each iron sulphate molecule needs 2 sodiul hydroxide molecules for reaction equilibrium that s the best i can do remembering the little chemistry i have left in my headest answer depending on the molar concentrations of reactants you shud produce ferrous hydroxide fe oh 2 as your principle product type feso4 naoh fe oh 2 into google and u shud easily find your answer
