The chemical reaction for the formation of Fe-Fe3O4-Fe-FeSO4-Fe(OH)2-Fe(OH)3 is:
4Fe + 3O2 → 2Fe3O42Fe3O4 + 3H2SO4 → FeSO4 + 2Fe2O3 + 3H2OFeSO4 + 2NaOH → Fe(OH)2 + Na2SO4Fe(OH)2 + 1/2O2 + H2O → Fe(OH)3
Therefore, the overall reaction can be written as:
4Fe + 3O2 + 6H2SO4 + 4NaOH → 2Fe3O4 + 6H2O + 4Na2SO4 + 4FeSO4 + 4Fe(OH)2 + 4Fe(OH)3
