What happens when aluminium sulphate is strongly heated in a test tube . Pls answer fast . Donot send related links. Its urgent..

Dear Student,

Aluminium Sulphate naturally exists in mainly 2 Hydrated form i.e. Aluminium Sulphate Hexadecahydrate [Al₂(SO₄)₃.16H₂O] and Aluminium Sulphate Octadecahydrate [Al₂(SO₄)₃.18H₂O].

So, when we heat the hydrated salt of Aluminium Sulphate then it loses its Water of Crystallization (18H₂O or 16H₂O) and forms Anhydrous Aluminium Sulphate.

Reaction Involved:

Al₂(SO₄)₃.18H₂O $\stackrel{∆}{\to }$ Al₂(SO₄)₃ + 18H₂O
Al₂(SO₄)₃.16H₂O $\stackrel{∆}{\to }$ Al₂(SO₄)₃ + 16H₂O

Hope this information clears your doubts about the topic.

Keep asking!!
