Aluminum sulfate is produced by reacting aluminum hydroxide with sulfuric acid or by treating aluminum-containing ores with sulfuric acid. It can also be obtained from less pure starting materials like bauxite.
Alum can be created through one of several chemical processes. One is by adding aluminum hydroxide Al (OH) 3 to sulfuric acid H 2 SO 4. The chemical reaction is: 2 Al (OH)3 + 3 H2SO4 → Al2(SO4)3 + 6H2O.
The process typically involves the addition of coagulants that destabilize particles, leading to agglomeration and subsequent settling. Aluminum sulfate, a common coagulant, introduces aluminum ions (Al³⁺) into the water, which act as bridges between negatively charged particles, facilitating the formation of larger aggregates, or flocs.
