The acid is prepared by the reaction of chlorosulfuric acid with hydrogen peroxide: [3] 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 ...
The lead chamber process for sulfuric acid production was abandoned, partly because it could not produce sulfur trioxide or concentrated sulfuric acid directly due to corrosion of the lead, and absorption of NO 2 gas. Until this process was made obsolete by the contact process, oleum had to be obtained through indirect methods.
Disulfuric acid (alternative spelling disulphuric acid) or pyrosulfuric acid (alternative spelling pyrosulphuric acid), also named oleum, is a sulfur oxoacid. [3] It is a major constituent of fuming sulfuric acid, oleum , and this is how most chemists encounter it.
Peroxymonosulfuric acid, also known as persulfuric acid, peroxysulfuric acid is the inorganic compound with the formula H 2 SO 5. It is a white solid. It is a component of Caro's acid, which is a solution of peroxymonosulfuric acid in sulfuric acid containing small amounts of water. [4] Peroxymonosulfuric acid is a very strong oxidant (E 0 = +2 ...
Pyrophosphoric acid, also known as diphosphoric acid, is the inorganic compound with the formula H 4 P 2 O 7 or, more descriptively, [(HO) 2 P(O)] 2 O. Colorless and odorless, it is soluble in water, diethyl ether, and ethyl alcohol.
Disulfurous acid, metabisulfurous acid or pyrosulfurous acid is an oxoacid of sulfur with the formula H 2 S 2 O 5. Its structure is HO−S(=O) 2 −S(=O)−OH. The salts of disulfurous acid are called disulfites or metabisulfites. Disulfurous acid is, like sulfurous acid (H 2 SO 3), a phantom acid, which does not exist in the free state. [2]
You may want to think twice before adding soda to your shopping cart. New research shows that not only do sugary drinks increase your risk for serious conditions such as heart disease and type 2 ...
Alcohol oxidation is a collection of oxidation reactions in organic chemistry that convert alcohols to aldehydes, ketones, carboxylic acids, and esters. The reaction mainly applies to primary and secondary alcohols.
