binary copper chloride compound (monohydrochloride) whose formula CuCl, it is a salt of hydrochloric acid.This powder is generally white or green, very poorly soluble in water.Greenish tinge monochloride crystals due to the presence of divalent impurities substance called copper chloride ii.
the first time it was obtained in the great chemist Robert Boyle.This event occurred long ago, in 1666, and for scientists to use a simple metallic copper and divalent mercury chloride.Then, in 1799, Joseph Proust singled out monohydrochloride crystals dichloride.This reaction is a process of gradually heating the solution resulting copper chloride (II) lose some chlorine, approximately half of its availability.Branch dichloride monochloride was conducted by ordinary washing.
copper monochloride - is a white crystalline substance that is at a temperature 408 ° C changes the shape of the crystal lattice.Since this compound and melts and boils substantially without degradation of its chemical formula is sometimes written as Cu2Cl2.Monohydrochloride, however, as other copper compounds, toxic.
copper chloride compound whose formula is written as CuCl2, is externally dark brown single crystals of a wedge shaped.The interaction even with a very small amount of water crystals of the compound changes color: a dark brown, he consistently goes to green and then to blue.Interestingly, if such an aqueous solution to add quite a bit of hydrochloric acid, the crystals return to one of the intermediate states - become greenish.
substance Melting point equals 537 ° C, and at a temperature of 954 - 1032 ° C, it boils.The compound is soluble in materials such as water, alcohol, ammonia.Its density is 3.054 g / cm3.At a constant dilution solution and maintaining the temperature at 25 ° C the molar conductivity substance is 265.9 cm2 / mol.
obtained by exposing the copper chloride to copper chloride, and by carrying out the reaction of copper sulfate (II) with sulfuric acid.The industrial production is based on the firing mixtures of copper sulfides with sodium chloride.In this case, the reaction temperature should be ensured 550-600 ° C, whereby, apart from the substance in itself, reveals the presence of gaseous components, such as HCl, arsenic gases and sulfur compounds.Known industry where getting the copper chloride is carried out by initiating an exchange reaction between copper sulfate and BaCl2.
At a temperature 993 ° C, the substance decomposes into Cl2 and CuCl, its solubility in aqueous solutions, characterized by:
- when dissolved in an aqueous solution of 25-degree temperature is completely dissolved in 100 grams of water, 77.4 grams of copper chloride;
- when the solution temperature reaches 100 ° C it has dissolved 120 grams of the substance.In both cases, it is assumed that the density of CuCl2 was similar.
Copper chloride is widely used as a chemical catalyst component pyrotechnical mixtures in the production of a variety of mineral dyes.As ammonia solution is used as a flue gas analyzer, facilitates the calculation of the concentration and the level of carbon dioxide.Suitable dichloride and as a carrier of oxygen in various stages of chemical manufacture, such technology, for example, in the production of common organic dyes.
Sol copper chloride, at all sparingly soluble, capable of forming a series of crystalline.The concentrated solution of the substance has an ability to connection of nitric oxide, which is also widely used in the production of drugs and in the chemical industry.
