Aluminum hydroxide (Aluminium hydroxide), chemical formula Al (OH) 3, is a hydroxide of aluminum. Aluminum hydroxide can not only react with acid to form salt and water but also react with strong base to form salt and water, so it is also an amphoteric hydroxide. The chemical formula Al (OH) 3 is a hydroxide of aluminum. Because it has a certain acidity, it can also be called aluminate (H3AlO3). But what actually forms when reacting 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 the purpose.
