Produktbeschreibung

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online.Atomic hydrogen (or nascent hydrogen) is the species denoted by H (atomic), contrasted with dihydrogen, the usual ''hydrogen'' (H2) commonly involved in chemical reactions. It is claimed to exist transiently but long enough to effect chemical reactions. According to one claim, nascent hydrogen is generated in situ usually by the reaction of zinc with an acid, aluminium (Devarda''s alloy) with sodium hydroxide, or by electrolysis at the cathode. Being monoatomic, H atoms are much more reactive and thus a much more effective reducing agent than ordinary diatomic H2, but again the key question is whether H atoms exist in any chemically meaningful way under the conditions claimed. The concept is more popular in engineering and in older literature on catalysis. Atomic hydrogen is made of individual hydrogen atoms which are not bound together like ordinary hydrogen into molecules.
