alumiinisulfaatti

Alumiinisulfaatti is the Finnish name for aluminum sulfate. It is a chemical compound with the formula Al2(SO4)3. It is commonly found as a hydrated salt, with the general formula Al2(SO4)3·nH2O, where n typically ranges from 14 to 18. In its anhydrous form, it is a white crystalline solid.

Aluminum sulfate is produced industrially by reacting aluminum hydroxide with sulfuric acid. It is soluble in water and is often used in its aqueous solution. The compound has a wide range of applications due to its ability to act as a flocculant, coagulant, and astringent.

One of the primary uses of aluminum sulfate is in water treatment. It is added to raw water to help remove suspended particles and impurities. The aluminum ions form gelatinous precipitates that trap and settle out unwanted matter, clarifying the water. In the paper industry, aluminum sulfate is used as a sizing agent to improve the water resistance and printability of paper. It also helps to bind dyes and pigments.

Additionally, aluminum sulfate finds use in dyeing fabrics, as a component in antiperspirants, and in the production of other aluminum compounds. It is also used in some fire-resistant materials and as a soil amendment to lower soil pH. While generally considered safe when used appropriately, concentrated solutions can be irritating.
