Sodium oxide is a chemical compound with the formula Na 2 O.It is used in ceramics and glasses.It is a white solid but the compound is rarely encountered. Instead "sodium oxide" is used to describe components of various materials such as glasses and fertilizers which contain oxides that include sodium and other elements.
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
Crystal structure of rubidium oxide. Lithium oxide (Li 2 O) is the lightest alkali metal oxide and a white solid. It melts at 1570 °C. Sodium oxide (Na 2 O) is a white solid that melts at 1132 °C and decomposes at 1950 °C. It is a component of glass. Potassium oxide (K 2 O) is a pale yellow solid that decomposes at 350 °C.
In 1884, Svante Arrhenius proposed that a base is a substance which dissociates in aqueous solution to form hydroxide ions OH −. These ions can react with hydrogen ions (H + according to Arrhenius) from the dissociation of acids to form water in an acid–base reaction. A base was therefore a metal hydroxide such as NaOH or Ca(OH) 2.
Sodium methoxide, also called sodium methylate and sodium methanolate, is a white powder when pure. [6] It is used as an initiator of an anionic addition polymerization with ethylene oxide, forming a polyether with high molecular weight.
As a solid, sodium methoxide is polymeric, with sheet-like arrays of Na + centers, each bonded to four oxygen centers. [3] The structure, and hence the basicity, of sodium methoxide in solution depends on the solvent. It is a significantly stronger base in DMSO where it is more fully ionized and free of hydrogen bonding. [4]
Sodium is a chemical element; it has symbol Na (from Neo-Latin natrium) and atomic number 11. It is a soft, silvery-white, highly reactive metal. Sodium is an alkali metal, being in group 1 of the periodic table. Its only stable isotope is 23 Na. The free metal does not occur in nature and must be prepared from compounds.
When dissolved in water, many metallic oxide form alkaline solutions, while many oxides of nonmetals form acidic solutions. For example, sodium oxide in solution forms the strong base sodium hydroxide, while phosphorus pentoxide in solution forms phosphoric acid.
