Structure of solid zinc peroxide. Zinc peroxide can be synthesized through the reaction of zinc chloride and hydrogen peroxide. [4] According to X-ray crystallography, the compound consists of octahedral Zn(II) centers bonded to six distinct peroxide (O 2 2-) ligands. The overall motif is very similar to that for iron pyrite (FeS 2). The ...
In alkali solution, zinc chloride converts to various zinc hydroxychlorides. These include [Zn(OH) 3 Cl] 2−, [Zn(OH) 2 Cl 2] 2−, [Zn(OH)Cl 3] 2−, and the insoluble Zn 5 (OH) 8 Cl 2 ·H 2 O. The latter is the mineral simonkolleite. [41] When zinc chloride hydrates are heated, hydrogen chloride evolves and hydroxychlorides result. [42]
Zinc chloride hydroxide monohydrate or more accurately pentazinc dichloride octahydroxide monohydrate is a zinc hydroxy compound with chemical formula Zn 5 (O H) 8 Cl 2 ·H 2 O.It is often referred to as tetrabasic zinc chloride (TBZC), basic zinc chloride, zinc hydroxychloride, or zinc oxychloride.
Fenton's reagent is a solution of hydrogen peroxide (H 2 O 2) and an iron catalyst (typically iron(II) sulfate, FeSO 4). [1] It is used to oxidize contaminants or waste water as part of an advanced oxidation process. Fenton's reagent can be used to destroy organic compounds such as trichloroethylene and tetrachloroethylene (perchloroethylene).
Crude zinc sulfide can be produced by igniting a mixture of zinc and sulfur. [8] More conventionally, ZnS is prepared by treating a mildly acidic solution of Zn 2+ salts with H 2 S: [9] Zn 2+ + S 2− → ZnS. This reaction is the basis of a gravimetric analysis for zinc. [10]
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
Specific reactions include the reaction of the metal with aqueous sulfuric acid: Zn + H 2 SO 4 + 7 H 2 O → ZnSO 4 ·7H 2 O + H 2. Pharmaceutical-grade zinc sulfate is produced by treating high-purity zinc oxide with sulfuric acid: ZnO + H 2 SO 4 + 6 H 2 O → ZnSO 4 ·7H 2 O. In aqueous solution, all forms of zinc sulfate behave identically.
Zinc hydroxide Zn 2 is an inorganic chemical compound. It also occurs naturally as 3 rare minerals: wülfingite (orthorhombic), ashoverite and sweetite (both tetragonal). Like the hydroxides of other metals, such as lead , aluminium , beryllium , tin and chromium , Zinc hydroxide (and Zinc oxide ), is amphoteric .
