Basic Introduction To Aluminum Hydroxide

Aluminum hydroxide is an inorganic substance with the chemical formula Al(OH)3, which is the hydroxide of aluminum. Aluminum hydroxide can react with acid to form salt and water, and can react with strong base to form salt and water, so it is an amphoteric hydroxide. Because of its certain acidity, it can also be called aluminate (H3AlO3). However, what is actually formed when it reacts with a base is tetrahydroxyaluminate ([Al(OH)4]-). Therefore, it is usually regarded as metaaluminate monohydrate (HAlO2·H2O), which is divided into two types: industrial grade and pharmaceutical grade.
