उत्तर
| Iron (II) sulphate | Iron (III) sulphate | |
| 1. | On adding ammonium hydroxide, a dirty green precipitate of iron(II) hydroxide, Fe(OH)2, is formed. | On adding ammonium hydroxide, a reddish-brown precipitate of iron(III) hydroxide, Fe(OH)3, is formed. |
| 2. | The precipitate is insoluble in excess ammonium hydroxide and gradually turns brown on exposure to air. | The precipitate is insoluble in excess ammonium hydroxide. |
| 3. | \[\ce{\underset{\text{(Light green solution)}}{FeSO4} + 2NH4OH ->\underset{\text{(Dirty green ppt.)}}{Fe(OH)2} + (NH4)2SO4}\] | \[\ce{\underset{\text{(Yellow solution)}}{FeCl3} + 3NH4OH ->\underset{\text{(Reddish brown ppt.)}}{Fe(OH)3} + NH4Cl}\] |
