What is the formula for aluminum hydroxide?

The chemical formula for aluminum hydroxide is Al(OH)3. It is a white, odorless, crystalline powder that is insoluble in water. Aluminum hydroxide is commonly used as an antacid to relieve symptoms of heartburn, acid indigestion, and upset stomach. It works by neutralizing excess stomach acid and protecting the stomach lining.

Aluminum hydroxide is also used in the production of aluminum metal, as a flame retardant in plastics and rubber, and as a filler in certain types of ceramics. It has a molar mass of 78.0 g/mol and a density of 2.42 g/cm3.

In its natural state, aluminum hydroxide can be found as the minerals gibbsite, bayerite, and nordstrandite. It can be synthesized by reacting aluminum chloride with sodium hydroxide, resulting in the formation of aluminum hydroxide precipitate.
