About this deal

NH 4] 2S 2O 4 was itself obtained by the electrolysis of a solution of ammonium bisulfate ( [NH 4]HSO 4) in sulfuric acid.

Ways to use hydrogen peroxide Hydrogen peroxide forms stable adducts with urea ( Hydrogen peroxide - urea), sodium carbonate ( sodium percarbonate) and other compounds. [8] An acid-base adduct with triphenylphosphine oxide is a useful "carrier" for H 2O 2 in some reactions. The bleaching effect of peroxides and their salts on natural dyes had been known since Thénard's experiments in the 1820s, but early attempts of industrial production of peroxides failed. The first plant producing hydrogen peroxide was built in 1873 in Berlin. The discovery of the synthesis of hydrogen peroxide by electrolysis with sulfuric acid introduced the more efficient electrochemical method. It was first commercialized in 1908 in Weißenstein, Carinthia, Austria. The anthraquinone process, which is still used, was developed during the 1930s by the German chemical manufacturer IG Farben in Ludwigshafen. The increased demand and improvements in the synthesis methods resulted in the rise of the annual production of hydrogen peroxide from 35,000 tonnes in 1950, to over 100,000 tonnes in 1960, to 300,000 tonnes by 1970; by 1998 it reached 2.7 million tonnes.

The approximately 100° dihedral angle between the two O–H bonds makes the molecule chiral. It is the smallest and simplest molecule to exhibit enantiomerism. It has been proposed that the enantiospecific interactions of one rather than the other may have led to amplification of one enantiomeric form of ribonucleic acids and therefore an origin of homochirality in an RNA world. [12] A commercially viable rouote hydrogen peroxide by the reaction of hydrogen with oxygen favours production of water but can be stopped at the peroxide stage. [34] [35] One economic obstacle has been that direct processes give a dilute solution uneconomic for transportation. None of these has yet reached a point where it can be used for industrial-scale synthesis. Peroxide has serious bleaching power, making it an effective stain remover. But don’t use it on colored items. And always test it in a hidden area first.
