Aluminium Hydroxide reacts with acids to produce a Aluminium salt:

Hydrochloric Acid + Aluminium Hydroxide → Aluminium Chloride + Water

6HCl + 2Al(OH)₃ → 2AlCl₃ + 3H₂O

Sulphuric Acid + Aluminium Hydroxide → Aluminium Sulphate + Water

3H₂SO₄ + 2Al(OH)₃ → Al₂(SO₄)₃ + 6H₂O

Nitric Acid + Aluminium Hydroxide → Aluminium Nitrate + Water

6HNO₃ + 2Al(OH)₃ → 2Al(NO₃)₃ + 3H₂O
