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 percarbonate or sodium carbonate peroxide is a chemical substance with empirical formula Na 2 H 3 CO 6. It is an adduct of sodium carbonate ("soda ash" or "washing soda") and hydrogen peroxide (that is, a perhydrate) whose formula is more properly written as 2 Na 2 CO 3 · 3 H 2 O 2. It is a colorless, crystalline, hygroscopic and water ...
Unit cell of sodium peroxide Na 2 O 2. The sodium ions are violet and the peroxide ions in red. In chemistry, metal peroxides are metal-containing compounds with ionically- or covalently-bonded peroxide (O 2− 2) groups. This large family of compounds can be divided into ionic and covalent peroxide.
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 – Na 2 O 2; Sodium peroxycarbonate – Na 2 CO 4; Sodium perrhenate – NaReO 4; Sodium persulfate – Na 2 S 2 O 8; Sodium phosphate; see trisodium phosphate – Na 3 PO 4; Sodium selenate – Na 2 O 4 Se; Sodium selenide – Na 2 Se; Sodium selenite – Na 2 SeO 3; Sodium silicate – Na 2 SiO 3; Sodium sulfate – Na 2 SO 4 ...
In chemistry, main group peroxides are peroxide derivatives of the main group elements. Many compounds of the main group elements form peroxides ( R−O−O−R' ), and a few are of commercial significance.
A pyrotechnic composition is a substance or mixture of substances designed to produce an effect by heat, light, sound, gas/smoke or a combination of these, as a result of non-detonative self-sustaining exothermic chemical reactions. Pyrotechnic substances do not rely on oxygen from external sources to sustain the reaction.
Sodium-calcium alloys are by-products of the electrolytic production of sodium from a binary salt mixture of NaCl-CaCl 2 and ternary mixture NaCl-CaCl 2-BaCl 2. Calcium is only partially miscible with sodium, and the 1-2% of it dissolved in the sodium obtained from said mixtures can be precipitated by cooling to 120 °C and filtering. [25]
