Basic oxides are oxides that show basic properties, in opposition to acidic oxides. A basic oxide can either react with water to form a base, or with an acid to form a salt and water in a neutralization reaction.[according to whom?]
Examples include:
Sodium oxide, which reacts with water to produce sodium hydroxide
Magnesium oxide, which reacts with hydrochloric acid to form magnesium chloride
Copper(II) oxide, which reacts with nitric acid to form copper nitrate
with potassium ions coordinated to 4 oxide ions and oxide ions coordinated to 8 potassium. K2O is a basicoxide and reacts with water violently to produce...
strontium carbonate SrCO3. It is a strongly basicoxide. About 8% by weight of cathode ray tubes is strontium oxide, which has been the major use of strontium...
an oxide can be reasonably assumed by its accompanying constituents. Less electronegative elements tend to form basicoxides such as sodium oxide and...
Aluminium oxide (or aluminium(III) oxide) is a chemical compound of aluminium and oxygen with the chemical formula Al2O3. It is the most commonly occurring...
Ethylene oxide is an organic compound with the formula C2H4O. It is a cyclic ether and the simplest epoxide: a three-membered ring consisting of one oxygen...
Calcium oxide (formula: CaO), commonly known as quicklime or burnt lime, is a widely used chemical compound. It is a white, caustic, alkaline, crystalline...
disperses in basic solutions or can be dispersed by sonication in polar solvents to yield monomolecular sheets, known as graphene oxide by analogy to...
Zinc oxide is an inorganic compound with the formula ZnO. It is a white powder which is insoluble in water. ZnO is used as an additive in numerous materials...
amphoteric oxides or hydroxides. Aluminium oxide (Al2O3) is an example of an amphoteric oxide. Amphoterism depends on the oxidation states of the oxide. Amphoteric...
Magnesium oxide (MgO), or magnesia, is a white hygroscopic solid mineral that occurs naturally as periclase and is a source of magnesium (see also oxide). It...
it almost always has an oxidation state of +2. It reacts readily with air to form a thin passivation coating of magnesium oxide that inhibits further corrosion...
natural process that converts a refined metal into a more chemically stable oxide. It is the gradual deterioration of materials (usually a metal) by chemical...
Cadmium oxide is an inorganic compound with the formula CdO. It is one of the main precursors to other cadmium compounds. It crystallizes in a cubic rocksalt...
may also react with limes and basicoxides. Silica refractories are refractories containing more than 93% silicon oxide (SiO2). They are acidic, have...
heating to about 400 °C. The most common oxidation states of platinum are +2 and +4. The +1 and +3 oxidation states are less common, and are often stabilized...
to zinc oxide: For further processing two basic methods are used: pyrometallurgy or electrowinning. Pyrometallurgy processing reduces zinc oxide with carbon...
Unlike the oxides formed by the other Group 2 elements (alkaline earth metals), beryllium oxide is amphoteric rather than basic. Beryllium oxide formed at...
Triphenylphosphine oxide (often abbreviated TPPO) is the organophosphorus compound with the formula OP(C6H5)3, also written as Ph3PO or PPh3O (Ph = C6H5)...
Yttrium barium copper oxide (YBa2Cu3O7) consists of both Cu(II) and Cu(III) centres. Like oxide, fluoride is a highly basic anion and is known to stabilize...
When burned in air, it forms primarily sodium peroxide with some sodium oxide. Sodium tends to form water-soluble compounds, such as halides, sulfates...
