Clemmensen reduction is a chemical reaction described as a reduction of ketones or aldehydes to alkanes using zinc amalgam and concentrated hydrochloric acid (HCl). [1] [2] This reaction is named after Erik Christian Clemmensen, a Danish-American chemist. [3] Scheme 1: Reaction scheme of Clemmensen Reduction.
Zincates are anionic zinc complexes. Related to the preparation of Lucas' reagent , tetrachlorozincates are often generated by combining hydrochloric acid and zinc chloride . A related anion is [Zn 2 Cl 6 ] 2− , in which again Zn(II) adopts a tetrahedral geometry.
Strong acids, such as hydrochloric or sulfuric acid, can remove the passivating layer and the subsequent reaction with the acid releases hydrogen gas. [51] Zinc chemistry resembles that of the late first-row transition metals, nickel and copper, [53] as well as certain main group elements.
Zinc compounds are chemical compounds containing the element zinc which is a member of the group 12 of the periodic table. The oxidation state of zinc in most compounds is the group oxidation state of +2. Zinc may be classified as a post-transition main group element with zinc(II). Zinc compounds are noteworthy for their nondescript appearance ...

Acidic drain cleaners usually contain sulfuric acid at a high concentration which turns a piece of pH paper red and chars it instantly. Apart from grease and hair, an acidic drain cleaner containing sulfuric acid can be also used to dissolve tissue paper inside water pipes. Acidic drain cleaners usually contain sulfuric acid at high ...
It is assumed that the reported solubility of zinc aspartate in diluted hydrochloric acid will allow its dissociation and absorption in the stomach. However, it was not clear if further absorption could take place in the intestine considering its reported insolubility in water. [2]
It is updated every five years and its latest 11th [2] version of the system groups products into 45 classes (classes 1-34 include goods and classes 35-45 embrace services), and allows users seeking to trademark a good or service to choose from these classes as appropriate. Since the system is recognized in numerous countries, this makes ...
