IMPORTANT DATA
Physical State; Appearance Routes of Exposure
ODOURLESS WHITE, LUSTROUS CRYSTALS OR POWDER. The substance can be absorbed into the body by inhalation
and by ingestion.
Chemical Dangers
Inhalation Risk
The substance decomposes on heating or on burning
producing toxic and corrosive fumes including sulfur oxides. Evaporation at 20C is negligible; a harmful concentration of

TLV (as Al soluble salt): ppm; 2 mg/m3 (ACGIH 1993-1994). The substance irritates the eyes, the skin and the respiratory
tract. Corrosive on ingestion.
PHYSICAL PROPERTIES
Melting point (decomposes): 770C Solubility in water: good
Relative density (water = 1): 2.71
ENVIRONMENTAL DATA
This substance may be hazardous to the environment; special attention should be given to fish.
NOTES
Cake alum, pickle alum, filter alum, papermaker's alum and pearl alum are other common names of aluminium sulfate. Occurs in
nature as the mineral alunogenite.
