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. Sodium oxide is a ...
White or light yellow sodium peroxide (Na 2 O 2) is formed when metallic sodium is burned in oxygen. Each oxygen atom in its peroxide ion may have a full octet of 4 pairs of electrons. [6] Superoxides are a class of compounds that are very similar to peroxides, but with just one unpaired electron for each pair of oxygen atoms (O − 2). [6]
Sodium peroxide is an inorganic compound with the formula Na 2 O 2.This yellowish solid is the product of sodium ignited in excess oxygen. [3] It is a strong base. This metal peroxide exists in several hydrates and peroxyhydrates including Na 2 O 2 ·2H 2 O 2 ·4H 2 O, Na 2 O 2 ·2H 2 O, Na 2 O 2 ·2H 2 O 2, and Na 2 O 2 ·8H 2 O. [4] The octahydrate, which is simple to prepare, is white, in ...
Sodium superoxide (NaO 2) is a yellow-orange solid that melts at 551.7 °C. It is made by the high-pressure oxidation of sodium peroxide. Potassium superoxide (KO 2) is a yellow solid that decomposes at 560 °C. It is used as a CO 2 scrubber, H 2 O dehumidifier, and O 2 generator in rebreathers, spacecraft, submarines, and spacesuit life ...
Example of a reduction–oxidation reaction between sodium and chlorine, with the OIL RIG mnemonic [1] Redox ( / ˈ r ɛ d ɒ k s / RED -oks , / ˈ r iː d ɒ k s / REE -doks , reduction–oxidation [ 2 ] or oxidation–reduction [ 3 ] : 150 ) is a type of chemical reaction in which the oxidation states of the reactants change.

Chemical reactions are usually characterized by a chemical change, and they yield one or more products, which usually have properties different from the reactants. Reactions often consist of a sequence of individual sub-steps, the so-called elementary reactions, and the information on the precise course of action is part of the reaction mechanism.
A basic oxide, also called a base anhydride (meaning "base without water"), is usually formed in the reaction of oxygen with metals, especially alkali (group 1) and alkaline earth (group 2) metals. Both of these groups form ionic oxides that dissolve in water to form basic solutions of the corresponding metal hydroxide :
The main use of sodium iodate in everyday life is in iodised salt. The other compounds which are used in iodised table salt are potassium iodate, potassium iodide, and sodium iodide. Sodium iodate comprises 15 to 50 mg per kilogram of applicable salt. Sodium iodate is also used as a dough conditioner to strengthen the dough.
