Food Grade Aluminum Potassium Sulfate/Potassium Salt Alum/Potassium Alum Powder
Aluminum sulfate (chemical formula: Al2 (SO4) 3) is a widely used industrial reagent, which is usually confused with alum. Aluminum sulfate is usually used as a flocculant in the purification of drinking water and sewage treatment equipment, as well as in the paper industry.
It is very soluble in water. Aluminum sulfate is insoluble in pure sulphuric acid, and soluble in sulphuric acid solution together with sulphuric acid. So the solubility of aluminium sulfate in sulphuric acid is the solubility of aluminium sulfate in water. Not easy to weathering and loss of crystalline water, relatively stable, heating will lose water, high temperature will decompose into alumina and sulfur oxides.
