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.
The industrially most important aluminium hydride is lithium aluminium hydride (LiAlH 4), which is used in as a reducing agent in organic chemistry. It can be produced from lithium hydride and aluminium trichloride: [25] 4 LiH + AlCl 3 → LiAlH 4 + 3 LiCl. The simplest hydride, aluminium hydride or alane, is not as important.

Dissociation in chemistry is a general process in which molecules (or ionic compounds such as salts, or complexes) separate or split into other things such as atoms, ions, or radicals, usually in a reversible manner.
Aluminium does not experience the inert-pair effect, a phenomenon where valence s electrons are poorly shielded from nuclear charge due to the presence of filled d and f orbitals. [1] As such, aluminium (III) ( Al 3 + {\displaystyle {\ce {Al^3+}}} ) is the much more common oxidation state for aluminium.
In chemistry, ion association is a chemical reaction whereby ions of opposite electric charge come together in solution to form a distinct chemical entity. [1] [2] Ion associates are classified, according to the number of ions that associate with each other, as ion pairs, ion triplets, etc. Ion pairs are also classified according to the nature of the interaction as contact, solvent-shared or ...
Formal charges in ozone and the nitrate anion. In chemistry, a formal charge (F.C. or q*), in the covalent view of chemical bonding, is the hypothetical charge assigned to an atom in a molecule, assuming that electrons in all chemical bonds are shared equally between atoms, regardless of relative electronegativity.
z + is the charge number of the cation; z − is the charge number of the anion; e is the elementary charge, equal to 1.6022 × 10 −19 C; ε 0 is the permittivity of free space, equal to 8.854 × 10 −12 C 2 J −1 m −1; r 0 is the nearest-neighbor distance between ions; and
