| | Aluminium Sulfate Usage And Synthesis |
| Chemical Properties |
Aluminium sulfate is a colorless or white crystals. Odorless, slightly sweet taste. Because of containing iron etc, industrial product looks like a yellowish-green, tastes sour. It was Stable in the air, heated to 250 ℃ to lose crystal water, when heated above 700 ℃, begin decompose into aluminum oxide, sulfur trioxide and water vapor, etc. Soluble in water, aqueous solution is acidic.
| | Uses | Aluminium sulfate is soluble in water and is mainly used as a coagulating agent (promoting particle collision by neutralizing charge) in the purification of drinking water and wastewater treatment plants, and also in paper manufacturing.
| | Production Methods |
Aluminium sulfate may be made by adding aluminium hydroxide, Al(OH)3, to sulfuric acid, H2SO4:
2 Al(OH)3 + 3 H2SO4 → Al2(SO4)3 + 6 H2O
or by heating aluminium metal in a sulfuric acid solution
2 Al + 3 H2SO4 → Al2(SO4)3 + 3 H2↑
| | Health Hazard |
ADI not specified (FAO/WHO, 2001).
GRAS (FDA, §182.1125,2000).
LD50 6207mg/kg (mice, by mouth)
| | Chemical Reactivity |
Aluminium sulfate reacts with sodium bicarbonate to which foam stabilizer has been added, producing carbon dioxide for fire-extinguishing foams:
Al2(SO4)3 + 6 NaHCO3 → 3 Na2SO4 + 2 Al(OH)3 + 6 CO2
The carbon dioxide is trapped by the foam stabilizer and creates a thick foam which will float on top of hydrocarbon fuels and seal off access to atmospheric oxygen, smothering the fire.
| | Toxicity |

| | Source | Aluminium sulfate occurs in nature in minerals; alunite, KAl3(SO4)2(OH)6and natroalunite, NaAl3(SO4)2(OH)6. The anhydrous salt is used in food applications.
