What Is The Chemical Formula For Aluminium Hydroxide?

The chemical formula for aluminium hydroxide is Al(OH)3. It consists of one atom of aluminium (Al), which has a valence of +3, and three molecules of hydroxide (OH-), each containing one atom of oxygen (O) and one atom of hydrogen (H). The three hydroxide molecules combine with the single aluminium atom to form a stable compound that is insoluble in water.

Aluminium hydroxide is commonly used as an antacid to neutralize excess stomach acid and relieve symptoms of heartburn, indigestion, and upset stomach. It is also used in the production of aluminum metal, as a flame retardant in plastics, and as a water treatment chemical to remove impurities and contaminants from drinking water.
