Iron(II) hydroxide precipitate. A beaker with iron(II) hydroxide precipitate (Fe(OH)2) that was formed by adding 0.5M solution of sodium hydroxide (NaOH) to 0.2M solution of iron(II) sulphate (FeSO4). The reaction is FeSO4 + NaOH -> Fe(OH)2 + Na2SO4. Pure iron(II) hydroxide is white, however even trace amounts of oxygen make it greenish. | |
