Characteristic
Aluminum hydroxide, chemical formula of Al (OH) 3, is the aluminum hydroxide.Aluminum hydroxide is a kind of amphoteric hydroxide because it can react with acid to produce salt and water and strong base to produce salt and water.It is also called aluminic acid (H3AlO3) because of its acidity.
Chemical formula：Al(OH)3
Molar mass：78.00 g/mol
Appearance：White amorphous powder
Density：2.42 g/cm3, solid
Melting point：300 °C (572 °F; 573 K)
Solubility in water：0.0001 g/100 mL
Solubility product (Ksp)：3×10−34
Solubility：soluble in acids and alkalis

Application
As absorbent, in chromatography, manufacturing of glass, paper, inks, ceramics, lubricants, cosmeticsAluminum hydroxide is used as a desiccant powder, filler in paper, plastics, rubber and cosmetics. It is used as a smoke suppressant and mordant dye. It is also used in drugs as antacid and antihyperphosphatemic. It is also used as a Claus catalyst support for waterproof fabrics. It is an important starting material for the preparation of other aluminum compounds, calcined alumina, aluminum sulfate, polyaluminum chloride, zeolites, sodium aluminate, activated alumina and aluminum nitrate. In addition, it is used as a fire retardant.
