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.

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.
Ammonium iron (III) sulfate, NH 4 Fe (SO 4) 2 ·12 H 2 O, or NH 4 [Fe (H 2 O) 6] (SO 4) 2 ·6 H 2 O, also known as ferric ammonium sulfate (FAS) or iron alum, is a double salt in the class of alums, which consists of compounds with the general formula AB (SO 4) 2 · 12 H 2 O. [2] It has the appearance of weakly violet, octahedrical crystals.
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 ...
Aluminium hydroxide, Al (OH)3, is found in nature as the mineral gibbsite (also known as hydrargillite) and its three much rarer polymorphs: bayerite, doyleite, and nordstrandite. Aluminium hydroxide is amphoteric, i.e., it has both basic and acidic properties. Closely related are aluminium oxide hydroxide, AlO (OH), and aluminium oxide or ...
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.
The specific heat of the human body calculated from the measured values of individual tissues is 2.98 kJ · kg−1 · °C−1. This is 17% lower than the earlier wider used one based on non measured values of 3.47 kJ · kg−1· °C−1. The contribution of the muscle to the specific heat of the body is approximately 47%, and the contribution ...
