A l C l 3 achieves stability by forming a dimer. In trivalent state the compound is hydrolysed in water. A l C l 3 in acidified aqueous solution forms
  1. A l O H 3 + H C l
  2. [ A l H 2 O 6 3 + + 3 C l -
  3. A l C l 3 . 2 H 2 O
  4. A l 2 O 3 + H C l

Solution

A l C l 3 in acidified aqueous solution forms A l H 2 O 6 3 + ion.

A l C l 3 + 9 H 2 O → A l H 2 O 6 O H 3 + 3 H + + 3 C l - .
