Aluminium oxides or aluminum oxides are a group of inorganic compounds with formulas including aluminium (Al) and oxygen (O). Aluminium(I) oxide (Al 2 O)
Aluminium oxide (or aluminium(III) oxide) is a chemical compound of aluminium and oxygen with the chemical formula Al 2 O 3.It is the most commonly occurring of several aluminium oxides, and specifically identified as aluminium oxide.
The aluminium oxides, oxide hydroxides, and hydroxides can be summarized as follows: aluminium oxides. corundum (Al 2 O 3); aluminium oxide hydroxides diaspore (α-AlO(OH)) ...
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.
Amphiprotism is exhibited by compounds with both Brønsted acidic and basic properties. [3] A prime example is H 2 O. Amphiprotic molecules can either donate or accept a proton ( H + ). Amino acids (and proteins ) are amphiprotic molecules because of their amine ( −NH 2 ) and carboxylic acid ( −COOH ) groups.
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.
Sodium aluminate is an inorganic chemical that is used as an effective source of aluminium hydroxide for many industrial and technical applications. Pure sodium aluminate is a white crystalline solid having a formula variously given as NaAlO 2, NaAl(OH) 4 (), [3] Na 2 O·Al 2 O 3, or Na 2 Al 2 O 4.
