Aluminium chloride, also known as aluminium trichloride, is an inorganic compound with the formula AlCl3. It forms a hexahydrate with the formula [Al(H2O)6]Cl3, containing six water molecules of hydration. Both the anhydrous form and the hexahydrate are colourless crystals, but samples are … See more Anhydrous AlCl3 adopts three structures, depending on the temperature and the state (solid, liquid, gas). Solid AlCl3 has a sheet-like layered structure with cubic close-packed chloride ions. In … See more Anhydrous aluminium chloride is a powerful Lewis acid, capable of forming Lewis acid-base adducts with even weak Lewis bases such … See more Anhydrous aluminium chloride is not found as a mineral. The hexahydrate, however, is known as the rare mineral chloraluminite. A more complex, basic and hydrated aluminium chloride mineral is cadwaladerite.

WebThe pKa values give us a convenient measure of the acid strength. The lower the value the stronger the acid. The pKa value depends on the ease of breakdown of the acid molecule as well as the stability of the ions formed and their relative hydration energies. The carboxylic acids show a trend over the first three members that is broken with the ... WebNot exactly. AlCl3 is a powerful Lewis acid. It reacts vigorously and irreversibly with Lewis bases. With water it forms the hexaaquoaluminum(III) ion, Al(H2O)_6^3+. This means that it can no longer behave as a Lewis acid and is therefore …
