The waste solid, bauxite tailings, is removed and aluminium hydroxide is precipitated from the remaining solution of sodium aluminate. This aluminium hydroxide can be converted to aluminium oxide or alumina by calcination. [citation needed] The residue or bauxite tailings, which is mostly iron oxide, is highly caustic due to residual sodium ...
Hydroxyaluminium(I), also known as Aluminium(I) hydroxide, is an inorganic chemical with molecular formula AlOH. It consists of aluminium in the +1 oxidation state paired with a single hydroxide . It has been detected as a molecular substance in the envelope of an oxygen -rich red supergiant star , a place where substances containing metals or ...

An alum (/ ˈ æ l ə m /) is a type of chemical compound, usually a hydrated double sulfate salt of aluminium with the general formula X Al(SO 4) 2 ·12 H 2 O, 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 2 O.
Many metals (such as zinc, tin, lead, aluminium, and beryllium) form amphoteric oxides or hydroxides. Aluminium oxide (Al 2 O 3) is an example of an amphoteric oxide. Amphoterism depends on the oxidation states of the oxide. Amphoteric oxides include lead(II) oxide and zinc oxide, among many others. [5]
In chemistry, metal hydroxides are a family of compounds of the form M n+ (OH) n, where M is a metal. They consist of hydroxide (OH −) anions and metallic cations, [1] and are often strong bases. Some metal hydroxides, such as alkali metal hydroxides, ionize completely when dissolved.
Aluminium hydroxide oxide or aluminium oxyhydroxide, AlO(OH) is found as one of two well defined crystalline phases, which are also known as the minerals boehmite and diaspore. The minerals are important constituents of the aluminium ore , bauxite .
Aluminium hydroxide, Al(OH) 3, aluminium with three hydroxy groups attached, is a complete molecule, so it is not a "basic aluminium" compound. Aluminium acetate is a name for three salts in the solid state: dihydroxyaluminium aluminium acetate, hydroxyaluminium diacetate, and aluminium triacetate, Al(CH 3 CO 2) 3.
