Aluminum hydroxide is an inorganic substance with the chemical formula Al(OH)3, which is a hydroxide of aluminum. Aluminum hydroxide can react with acid to form salt and water and also with strong base to form salt and water, so it is an amphoteric hydroxide. Because it shows a certain degree of acidity, it can also be called aluminate (H3AlO3). But the actual reaction with alkali is tetrahydroxyaluminate ([Al(OH)4]-). Therefore, it is usually regarded as metaaluminate monohydrate (HAlO2·H2O), which is divided into industrial grade and pharmaceutical grade according to its use.
