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 ...
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.
One example involves sodium perborate, a commercially important bleaching agent with the formula Na 2 [(HO) 2 B] 2 (OO) 2)]. It acts by hydrolysis to give a boron-hydroperoxide: [16] [(HO) 2 B] 2 (OO) 2) 2− + 2 H 2 O ⇌ 2 [(HO) 3 B(OOH)] −. This hydrogen peroxide then releases hydrogen peroxide: [(HO) 3 B(OOH)] − + H 2 O ⇌ B(OH) − 4 ...
Typically aqueous sodium hydroxide solutions are used. [1] [2] It is an important type of alkaline hydrolysis. When the carboxylate is long chain, its salt is called a soap. The saponification of ethyl acetate gives sodium acetate and ethanol: C 2 H 5 O 2 CCH 3 + NaOH → C 2 H 5 OH + NaO 2 CCH 3
The peroxide group is marked in blue. R, R 1 and R 2 mark hydrocarbon moieties. The most common peroxide is hydrogen peroxide (H 2 O 2), colloquially known simply as "peroxide". It is marketed as solutions in water at various concentrations. Many organic peroxides are known as well. In addition to hydrogen peroxide, some other major classes of ...
Sodium persulfate is the inorganic compound with the formula Na 2 S 2 O 8. It is the sodium salt of peroxydisulfuric acid , H 2 S 2 O 8 , an oxidizing agent . It is a white solid that dissolves in water.
Hydroxyl radicals are also produced during UV-light dissociation of H 2 O 2 (suggested in 1879) and likely in Fenton chemistry, where trace amounts of reduced transition metals catalyze peroxide-mediated oxidations of organic compounds. In organic synthesis hydroxyl radicals are most commonly generated by photolysis of 1-Hydroxy-2(1H ...
Sodium peroxide (Na 2 O 2) is used to oxidize the sample that becomes soluble in a diluted acid solution. This method allows complete dissolution of numerous refractory compounds like chromite , magnetite , ilmenite , rutile , and even silicon , carbides , alloys , noble metals and materials with high sulfide contents.
