It occurs as the mineral covellite and is an ionic compound [3, 4]. CAS Number: 1317-40-4 / EC Number: 215-271-2 Company: Angstrom Sciences, Inc. Product Name: Copper(II) Sulfide Product Number: All applicable American Elements product codes, e.g. Source(s): https://shrinke.im/a0AzE. Solubility in . Cuprous sulfide is insoluble in water but soluble in ammonium…. Contents. Product […] Solubility product constant (K sp) (or the solubility product) is the product of the molar concentrations of the constituent ions, each raised to the power of its stoichiometric coefficient in the equilibrium equation.For instance, if a compound A a B b is in equilibrium with its solution secondary sulfide copper minerals, chalcocite and covellite. This information is not yet completed. The formation of copper thio-complexes in sulfide solutions has been recognized for many years, and the measured solubilities of certain copper sulfide minerals are attributed to these complexes. Сopper(II) sulfide; CAS: 1317-40-4; EC: 215-271-2; Synonym: copper(II) sulfide; Formula: CuS; Physical and chemical properties, preparation and purification methods and more at chemdb.net. C) 5.77x10^-36. Assuming the activity of the sulfide solid to be unity, the solubility relationship from (R1) can be described by: DATE OF LAST REVISION: 07/09/15. We are also the exclusive or select distributor for key manufacturers located throughout the world. In the case of the copper sulfide minerals, the formation of either copper(I) or copper(II) thio-complexes would have a similar effect of causing solubility in a region of potential that could be expected at the bottom of a tailings heap, below an orebody, or even in an anaerobic treatment wetlands as suggested by Gammons and Frandsen (2001). There are also implications in considering more … Insoluble in water, ethanol, hydrochloric acid ,dilute acids, sulfuric acid, alkali cyanides, aqueous ammonia and alkaline solutions. NACRES NA.23 It is one of a number of binary compounds of copper … In the production of copper two thirds of the molten copper sulfide is … C) 0.22 M K2S. Copper Sulfide Solubility. Preparation and reactions. Why is copper II sulfate soluble in water? Solubility is the property of a solid, liquid, or gaseous chemical substance called solute to dissolve in a solid, liquid, or gaseous solvent. DATE OF LAST REVISION: 07/09/15. CuS is a moderate conductor of electricity. Sigma-Aldrich offers a number of Copper(II) sulfide products. The sulfide solubility chart below demonstrates the solubility of the metal sulfide compounds. Copper Sulfide Empirical Formula. Some time after I published a technical paper on the measurement of copper in wine in 1983, I was called by a winemaker who wished to discuss the chemistry of copper additions to remove the aroma of hydrogen sulfide. However, it was later shown to be rather a cuprous compound, formula Cu+3S. Empirical Formula (Hill Notation) CuS . The Ksp of copper sulfide (CuS) is 8.0 × 10–37. It is insoluble in water but is decomposed by nitric acid. Cu 2 S can be prepared by heating copper strongly in sulfur vapour or H 2 S. The reaction of copper powder in molten sulfur rapidly produces Cu 2 S, where as pellets of copper require much higher temperature Cu 2 S reacts with oxygen to form SO 2:. [4] CuS is a moderate conductor of electricity. copper sulfide formula. Solubility in . COPPER SULFIDE . +Add Attachment Copper(II) sulfide powder, 99.99% trace metals basis Synonym: Copper Blue, Copper monosulfide, Cupric sulfide CAS Number 1317-40-4. Copper sulfide, for example, is a very insoluble compound and the presences of soluble sulfide precipitates the copper as it dissociates from the ammonical complex.
