Differentiate between:
Aqueous ferrous and ferric sulphate solution
Advertisements
Solution
| Aqueous ferrous | Ferric sulphate solution |
|
When ammonium solution is added to aqueous solution of ferrous sulphate a dirty green precipi tate of ferrous hydroxide is obtained which is insoluble in excess of ammonium solution. Hydroxide. \[\ce{FeSO4 + 2NH4OH -> (NH4)2SO4 + Fe(OH)2}\] |
On adding ammonium solution to ferric sulphate solution we get ammonium sulphate and reddish brown precipi tate of ferric hydroxide which is insoluble in excess of ammonium solution . \[\ce{Fe2(SO4)3 + 6NH4OH -> 3(NH4)2SO4 + 2Fe(OH)3}\] |
