Aluminum Hydroxide, often recognized by its chemical formula Al(OH)3, is a naturally occurring mineral known for its antacid properties. This white, crystalline substance also goes by the names of gibbsite, hydrargillite, or simply alumina hydrate. It falls under the category of inorganic compounds and is derived from aluminum, one of the most abundant elements on Earth.

Aluminium hydroxide is also called Aluminic acid or Aluminic hydroxide or Aluminium (III) hydroxide. It is found in nature in the form of mineral gibbsite and its polymorphs viz doyleite, nordstrandite, and bayerite. Aluminic hydroxide is an amorphous powder white. It is insoluble in water but soluble in alkaline and acidic solutions.
