About Aluminium Hydroxide
- Aluminium Hydroxide is a base.
- Aqueous Aluminium Hydroxide is an alkali.
- Aluminium Hydroxide is held together by ionic bonds.
- Aluminium Hydroxide has a giant ionic structure.
- 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
