Infobox references. Aluminium sulfate is a salt with the formula Al 2 (SO 4) 3. It is soluble in water and is mainly used as a coagulating agent (promoting particle collision by neutralizing charge) in the purification of drinking water [3][4] and wastewater treatment plants, and also in paper manufacturing.
2·12H. 2O. An alum (/ ˈæləm /) is a type of chemical compound, usually a hydrated double sulfate salt of aluminium with the general formula XAl (SO. 4) 2·12 H. 2O, such that X is a monovalent cation such as potassium or ammonium. [1] By itself, "alum" often refers to potassium alum, with the formula KAl (SO. 4) 2·12 H.
Aluminium's electropositive behavior, high affinity for oxygen, and highly negative standard electrode potential are all more similar to those of scandium, yttrium, lanthanum, and actinium, which have ds 2 configurations of three valence electrons outside a noble gas core: aluminium is the most electropositive metal in its group. [1] Aluminium ...
Aluminium (or aluminum in North American English) is a chemical element; it has symbol Al and atomic number 13. Aluminium has a density lower than that of other common metals, about one-third that of steel. It has a great affinity towards oxygen, forming a protective layer of oxide on the surface when exposed to air.
Infobox references. Ammonium aluminium sulfate, also known as ammonium alum or just alum (though there are many different substances also called "alum"), is a white crystalline double sulfate usually encountered as the dodecahydrate, formula (NH 4)Al (SO 4) 2 ·12H 2 O. It is used in small amounts in a variety of niche applications.
Potassium alum, potash alum, or potassium aluminium sulfate is a chemical compound first mentioned under various Sanskrit names in Ayurvedic medicinal texts such as charak samhita, sushrut samhita, and ashtang hridaya; is chemically defined as the double sulfate of potassium and aluminium, with chemical formula KAl(SO 4) 2.

Aluminium chlorohydrate. Aluminium chlorohydrate is a group of water-soluble, [1] specific aluminium salts having the general formula Al n Cl 3n−m(O H)m. It is used in cosmetics as an antiperspirant and as a coagulant in water purification. In water purification, this compound is preferred in some cases because of its high charge, which makes ...
