Aluminum sulfate (aluminum sulfate)

Characteristics:
• Chemical formula: Al2(SO4)3
• Manufacturer: Russia
• GOST 12966-85

Aluminum sulfate 18-hydrate is an inorganic substance containing 18 water molecules, has the appearance of a white solid powder, and may have plate-like inclusions. It dissolves in water and does not dissolve in alcohol, is not poisonous, but can be hazardous to health, does not explode or burn, but at high temperatures it emits dangerous gases.

Application

The most common uses of aluminum sulfate octadecahydrate are found in medicine and manufacturing:

used in production for pickling, dyeing, tanning, in pest control, as a soil oxidizer, in the paper industry, in the food industry as an additive E-520;
for research into Alzheimer's disease and Parkinson's disease - the role of aluminum in the emergence and development of these pathologies is clarified;
in medicine as a painkiller.

Receipt

It is rare in the natural environment - it can be found in the form of a mineral in volcanic rocks, and even more rarely, aluminum sulfate 18-hydrate is found in the form of an anhydrous salt. Therefore, to obtain a substance, a synthesis reaction is used:

2Al(OH)3 + 3H2SO4 → Al2(SO4)3 • 6H2O
