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 ...
An example SDS, including guidance for handling a hazardous substance and information on its composition and properties. A safety data sheet (SDS), [1] material safety data sheet (MSDS), or product safety data sheet (PSDS) is a document that lists information relating to occupational safety and health for the use of various substances and products.
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.
The anhydrous form of sodium stannate, Na 2 SnO 3, is recognised as a distinct compound with its own CAS Registry Number, [4] 12058-66-1, and a distinct material safety data sheet. [5] Alkali metal stannate compounds are prepared by dissolving elemental tin in a suitable metal hydroxide, in the case of sodium stannate by the reaction: [6]
Sodium superoxide is the inorganic compound with the formula Na O 2. [1] This yellow-orange solid is a salt of the superoxide anion. It is an intermediate in the oxidation of sodium by oxygen.
Osmium-containing residues are treated with sodium peroxide (Na 2 O 2) forming Na 2 [OsO 4 (OH) 2], which is soluble. When exposed to chlorine, this salt gives OsO 4. In the final stages of refining, crude OsO 4 is dissolved in alcoholic NaOH forming Na 2 [OsO 2 (OH) 4], which, when treated with NH 4 Cl, to give (NH 4) 4 [OsO 2 Cl 2].
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.
Potassium persulfate can be prepared by electrolysis of a cold solution potassium bisulfate in sulfuric acid at a high current density. [1] [4]2 KHSO 4 → K 2 S 2 O 8 + H 2. It can also be prepared by adding potassium bisulfate (KHSO 4) to a solution of the more soluble salt ammonium peroxydisulfate (NH 4) 2 S 2 O 8.
