The so-called aluminum hydroxide actually refers to the hydrate of
aluminum oxide. For example, the white colloidal precipitate
obtained by adding ammonia or alkali to the aluminum salt solution
has variable water content and uneven composition, and is
collectively referred to as hydrated alumina. Only by passing CO2
in the aluminate solution (containing Al(OH)4-ion) can the real
aluminum hydroxide be obtained.
Crystalized aluminum hydroxide is different from hydrated aluminum
oxide. It is hardly soluble in acid and will not be dehydrated when
heated to 373K. It can be converted into aluminum hydroxide
(AlO(OH)) after heating at 573K for 2 hours.
Aluminum hydroxide is an amphoteric hydroxide. Because of its two
ionization forms, it is not only a weak acid, which can have the
acid formula H3AlO3, but also a weak base, which can have the basic
chemical formula Al(OH)3. Aluminum hydroxide is amphiphilic and can
react with acids and alkalis. The acidity of aluminum hydroxide is
that it is a Lewis acid that can be added with OH-, thus reflecting
the basicity of Al(OH)3. Due to the presence of two ionizations,
two salts can be produced: two salts of aluminum:
⒈aluminum salt: Al3+ AlCl3 , KAl(SO4)
Their aqueous solutions are acidic due to the hydrolysis of Al3+.
AgNO3 and dilute nitric acid are added dropwise respectively. The
white precipitate is Cl-; the light yellow precipitate is Br-; the
yellow precipitate is I-2. Metaaluminate, AlO2 - NaAlO2,KAlO2.
Their aqueous solutions are alkaline:
AlO2- + 2H2O → Al(OH)3 + OH- When the two types of salts are mixed,
a double hydrolysis reaction occurs, forming
Al(OH)3 Al3+ +Al2-3 6H2O == 4Al(OH)3↓ Aluminum hydroxide mainly
has four specifications: 325 mesh, 800 mesh, 1250 mesh, and 5000
mesh. White powdery solid. Almost insoluble in water, it can
condense suspended solids in water and adsorb pigments.
