Question

Differentiate between:
Aqueous ferrous and ferric sulphate solution

✓

Answer

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. $FeSO _4+2 NH _4 OH \longrightarrow\left( NH _4\right)_2 SO _4+ Fe ( OH )_2$	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 . $Fe _2\left( SO _4\right)_3+6 NH _4 OH \longrightarrow 3\left( NH _4\right)_2 SO _4+2 Fe (\phi H )_3$
