The anhydrous compound features Hg 2+ in a highly distorted tetrahedral HgO 4 environment. Two Hg-O distances are 2.22 Å and the others are 2.28 and 2.42 Å. [5] In the monohydrate, Hg 2+ adopts a linear coordination geometry with Hg-O (sulfate) and Hg-O (water) bond lengths of 2.179 and 2.228 Å, respectively. Four weaker bonds are also ...
Mercury(II) nitrate is an inorganic compound with the chemical formula Hg(N O 3) 2. It is the mercury(II) salt of nitric acid HNO 3. It contains mercury(II) cations Hg 2+ and nitrate anions NO − 3, and water of crystallization H 2 O in the case of a hydrous salt. Mercury(II) nitrate forms hydrates Hg(NO 3) 2 ·xH 2 O.
The decomposition of Hg(SCN) 2 is exothermic on its own, and the CS 2 produced ignites easily and burns off. The C 3 N 4 product is a simplification; the actual product contains 0.5% hydrogen and is likely to consist of sheets of triazine rings linked by −N= and −NH− groups similar to g−C 3 N 4 and was found to contain nano-particles of ...
Molecular models of the different molecules active in Piranha solution: peroxysulfuric acid (H 2 SO 5) and hydrogen peroxide (H 2 O 2). Piranha solution, also known as piranha etch, is a mixture of sulfuric acid (H 2 SO 4) and hydrogen peroxide (H 2 O 2). The resulting mixture is used to clean organic residues off substrates, for example ...
The Denigés' reagent is a reagent used for qualitative analysis. It was developed in 1898 by Georges Denigés (December 25, 1859–February 20, 1951), a French biochemist. It was developed in 1898 by Georges Denigés (December 25, 1859–February 20, 1951), a French biochemist.
Mercury(II) chloride (or mercury bichloride [citation needed], mercury dichloride), historically also known as sulema or corrosive sublimate, [2] is the inorganic chemical compound of mercury and chlorine with the formula HgCl 2, used as a laboratory reagent. It is a white crystalline solid and a molecular compound that is very toxic to humans.
The direct reaction of O 2 with fuel is precluded by the oxygen reduction reaction, which produces water and adenosine triphosphate. Cytochrome c oxidase affects the oxygen reduction reaction by binding O 2 in a heme–Cu complex. In laccase, O 2 is engaged and reduced by a four-copper aggregate.
The Dakin oxidation (or Dakin reaction) is an organic redox reaction in which an ortho- or para-hydroxylated phenyl aldehyde (2-hydroxybenzaldehyde or 4-hydroxybenzaldehyde) or ketone reacts with hydrogen peroxide (H 2 O 2) in base to form a benzenediol and a carboxylate. Overall, the carbonyl group is oxidised, whereas the H 2 O 2 is reduced.
