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.
A pseudo alum is a double sulfate of the typical formula X SO 4 · Y 2 (SO 4) 3 ·22 H 2 O, such that X is a divalent metal ion, such as cobalt , manganese , magnesium (pickingerite) or iron (halotrichite or feather alum), and Y is a trivalent metal ion. [36] Double sulfates with the general formula X 2 SO 4 · Y 2 (SO 4) 3 ·24 H
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.

The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
Lead styphnate – C 6 HN 3 O 8 Pb; Lead tetrachloride – PbCl 4; Lead tetrafluoride – PbF 4; Lead tetroxide – Pb 3 O 4 [205] Lead titanate – PbTiO 3; Lead zirconate titanate – Pb[Ti x Zr 1−x]O 3 (e.g., x = 0.52 is lead zirconium titanate) Plumbane – PbH 4
Aluminium trichloride (AlCl 3) has a layered polymeric structure below its melting point of 192.4 °C (378 °F), but transforms on melting to Al 2 Cl 6 dimers with a concomitant increase in volume by 85% and a near-total loss of electrical conductivity
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.
