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 ...
Potassium superoxide is a source of superoxide, which is an oxidant and a nucleophile, depending on its reaction partner. [8]Upon contact with water, it undergoes disproportionation to potassium hydroxide, oxygen, and hydrogen peroxide:
The acid is prepared by the reaction of chlorosulfuric acid with hydrogen peroxide: 2 ClSO 3 H + H 2 O 2 → H 2 S 2 O 8 + 2 HCl. Another method is the electrolysis of moderately concentrated sulfuric acid (60-70%) with platinum electrodes at high current density and voltage: H 2 SO 4 + H 2 O → H 3 O + + HSO 4 − (dissociation of sulfuric acid)
Unlike other known decompositions of LiO 2, this reaction bypasses lithium peroxide. Occurrence. Like other superoxides, lithium superoxide is the product of a one-electron reduction of an oxygen molecule. It thus appears whenever oxygen is mixed with single-electron redox catalysts, such as p-benzoquinone. In batteries
At higher temperatures peroxide decomposition is faster, more polymerization occurs to heat the mixture, which in turn increases peroxide decomposition and polymerizes the monomer even faster. The container dissipates heat more slowly in a higher-temperature environment, so at some critical temperature heat is generated by polymerization faster ...
Strontium peroxide is an inorganic compound with the formula Sr O 2 that exists in both anhydrous and octahydrate form, both of which are white solids. The anhydrous form adopts a structure similar to that of calcium carbide .
Between 280 and 360 °C, Rubidium superoxide will decompose, leaving not rubidium sesquioxide (Rb 2 O 3), but rather rubidium peroxide (Rb 2 O 2). 2 RbO 2 (s) → Rb 2 O 2 (s) + O 2 (g) An even more oxygen rich compound, that of rubidium ozonide (RbO 3) can be created using RbO 2. Properties
Hydrogen peroxide–urea (also called Hyperol, artizone, urea hydrogen peroxide, and UHP) is a white crystalline solid chemical compound composed of equal amounts of hydrogen peroxide and urea. It contains solid and water -free hydrogen peroxide, which offers a higher stability and better controllability than liquid hydrogen peroxide when used ...
