Aluminium chloride, also known as aluminium trichloride, is an inorganic compound with the formula AlCl 3. It forms a hexahydrate with the formula [Al(H 2 O) 6 ]Cl 3 , containing six water molecules of hydration .
It is an evenly balanced mixture of aluminium sulfate and aluminium acetate.It can be used as a mordant, which is a substance used to set dyes on fabrics [3] that typically contains a polyvalent metal ion like aluminium or iron, [4] In mixtures with basic aluminium diacetate or aluminium sulfacetate, aluminium triacetate has been used as a mordant with alizarin dye.

Pure cryolite has a melting point of 1009 ± 1 °C (1848°F). With a small percentage of alumina dissolved in it, its melting point drops to about 1000 °C (1832°F). Besides having a relatively low melting point, cryolite is used as an electrolyte because, among other things, it also dissolves alumina well, conducts electricity, dissociates electrolytically at higher voltage than alumina, and ...
A metal ion in aqueous solution or aqua ion is a cation, dissolved in water, of chemical formula [M(H 2 O) n] z+.The solvation number, n, determined by a variety of experimental methods is 4 for Li + and Be 2+ and 6 for most elements in periods 3 and 4 of the periodic table.
The first solvation shell of a sodium ion dissolved in water. An aqueous solution is a solution in which the solvent is water. It is mostly shown in chemical equations by appending (aq) to the relevant chemical formula. For example, a solution of table salt, also known as sodium chloride (NaCl), in water would be represented as Na + (aq) + Cl ...
Tetrachloroaluminate [AlCl 4] − is an anion formed from aluminium and chlorine.The anion has a tetrahedral shape and is isoelectronic with silicon tetrachloride.Some tetrachloroaluminates are soluble in organic solvents, creating an ionic non-aqueous solution, making them suitable as component of electrolytes for batteries.
A variety of compounds of empirical formula AlR 3 and AlR 1.5 Cl 1.5 exist. [22] The aluminium trialkyls and triaryls are reactive, volatile, and colorless liquids or low-melting solids. They catch fire spontaneously in air and react with water, thus necessitating precautions when handling them.
The hexahydrate is obtained from a reaction between metallic aluminum or aluminum hydroxide with hydrogen iodide or hydroiodic acid. Like the related chloride and bromide, AlI 3 is a strong Lewis acid and will absorb water from the atmosphere.
