Product details
Product Description
Product name: Aluminium Sulphate or Aluminum Sulfate
Shape: Flakes or Granular or Powder.
EINECS NO.: 233-135-0
CAS No.: 10043-01-3
HS.Code: 28332200
Molecular Formula: Al2(SO4)3
Appearance: It is white or grey odorless, easily hygroscopic shiny crystals or powder.
Apt to cake after moisture absorption when laid in air for a long time.A little green because of Fe2+, yellow when Fe2+ is oxided to Fe3+. Soluble in water easily, and water solution is acid.

Non Ferric Aluminum Sulphate has a wide range of uses in industry. Alum can be used to clean drinking water, and it is also used in tanning, printing and dyeing, paper making and other industries. Aluminum sulfate, aluminum oxide or aluminum hydroxide and sulfuric acid can produce aluminum sulfate.
Physical properties:
Appearance and properties: white crystals, sweet taste; solubility: soluble in water, insoluble in ethanol, etc.
Industrial products are off-white flakes, granules or lumps, with light green color due to low iron salts, and yellowing of the surface due to oxidation of low iron salts. The crude product is an off-white porous material with fine crystal structure.
It is very soluble in water. Aluminum sulfate cannot be dissolved in pure sulfuric acid (just coexist). It dissolves in water together with sulfuric acid in sulfuric acid solution. Therefore, the solubility of aluminum sulfate in sulfuric acid is the solubility of aluminum sulfate in water.
