Including anhydrous
and hydrous(*8 crystal water) type. Usually, the crystal separated
out from aqueous solution at the normal temperature is Al 2 (SO 4 )
3.*8H 2 O; When weathering, the average molecular structure is Al 2
(SO 4 ) 3.*4H 2 O, may appear white powdery, with bright flake or
crystalline flake let, odorless, to change the taste from sweetness
to slight astringency.
Alumina is often as flocculating
agent, used for drinking water purification and sewage treatment
equipment, and can also be used to in papermaking industry. Natural
conditions, almost no water in aluminium salt forms exist. It will
form a series of hydrate, including *6 water vitriolic is the most
common.  Papermaker's alum is aluminum sulfate. Concentrations and addition amounts are usually based on either (a) the equivalent amount of Al2O3 or (b) the equivalent amount of the hydrate, Al2O3.*4H2O. Alum is most commonly delivered as a liquid concentration, having a solids level of 8.3% as Al2O3 or about *0% as hydrate. Alum solutions are acidic. For instance, a 1% solution has a pH of around 3. Ionic species present in alum solutions are highly dependent on the degree of reaction with hydroxyl ions. It is tempting to say that "the composition is pH-dependent."
