- Description:
Product name: Aluminium Sulphate
Molecular Formula: AL2(SO4)3
EINECS No.:233-135-0
CAS NO.:10043-01-3
- Characteristics:
Aluminum sulfate is an odorless, white, or off-white crystalline solid or powder. The compound is made by adding aluminum hydroxide to sulfuric acid. It’s hygroscopic, which means it has the ability to absorb and hold water molecules from the surrounding atmosphere. It’s also water soluble and not volatile or flammable. Aluminum sulfate is extremely acidic. When combined in solution with water its pH can be less than two, which can make it capable of burning human skin and corroding metal.
