Copper(II) chloride Usage And Synthesis
Physical PropertiesCopper(II) chloride, CuCl2 is an anhydrous, brown solid copper salt which is soluble in water and gives a brownish aqueous solution when concentrated. When diluted, the solution changes its colour to green and then blue. CuCl2 is formed when copper(II) oxide, CuO, is treated with hydrochloric acid, HCl: CuO + 2HCI→CuCl2 + H2O.
Copper(II) chloride dihydrate
The anhydrous form constitutes yellow to brown monoclinic crystals. It is hygroscopic; forms dihydrate on exposure to moist air; density 3.40 g/cm3; melts around 630°C with decomposition; soluble in water, ethanol and acetone.
The dihydrate exists as greenish blue orthorhombic crystals; density 2.51 g/cm3; decomposes at 100°C; is very soluble in water and ethanol (solubility greater than anhydrous salt in these solvents); also soluble in acetone; insoluble in ether.
UsesCopper(II) chloride is used as a mordant in dyeing and printing of fabrics; as an ingredient of isomerization and cracking catalysts; and as a desulfurizing and deodorizing agent in petroleum industry. Other important applications are in copper plating of aluminum; in tinting-baths for iron and tin; in pigments for ceramics and glasses; as a fixer and desensitizer reagent in photography; in mercury extraction from ores; in laundry-marking and invisible inks; and in manufacture of several copper salts.
PreparationCopper(II) chloride may be synthesized by heating elemental copper with chlorine:
Cu + Cl2 →CuCl2
Alternatively, it may be prepared by treating copper carbonate with hydrochloric acid followed by crystallization:
CuCO3 + 2HCl → CuCl2 + CO2 + H2O
In the above preparation, the hydrate of the salt crystallizes, precipitates, and may be dehydrated by heating under vacuum.
ReactionsWhen heated above 300°C, copper(II) chloride partially decomposes to copper( I) chloride and chlorine:
2CuCl2→ 2CuCl + Cl
Also, it is reduced to CuCl and elemental copper when treated with reducing agents.
Fluorination with fluorine produces copper(II) fluoride, CuF2. Adding potassium ferrocyanide to CuCl2 aqueous solution precipitates out reddish brown cupric ferrocyanide. Reaction with caustic soda forms blue cupric hydroxide:
CuCl2 + 2NaOH → Cu(OH)2 + 2NaCl
Black copper(II) sulfide, CuS, is obtained when hydrogen sulfide is passed through dissolved CuCl2.
CuCl2 forms several copper(II) complexes with several types of ligands in aqueous solutions.
Chemical PropertiesCupric Chloride, brown-yellow powder, quite soluble in cold H2O or alcohol, very soluble in hot H2O. Catalyst for several organic syntheses, including production of vinyl chloride monomer.
Chemical PropertiesCupric chloride, CuCI2, also known as copper chloride, is a yellowish- brown solid that is soluble in water and alcohol. The dihydrate of cupric chloride, CUCI2·H20, is a green crystalline solid that is soluble in water. Cupric chloride is used in the textile industry as a mordant in the dyeing and printing of fabrics. Itis also used in refining gold,silver,and copper.
UsesSupplement (trace mineral).
DefinitionChEBI: An inorganic chloride of copper in which the metal is in the +2 oxidation state.
General DescriptionCupric chloride and ammonia contains various concentrations of cupric chloride in ammonium hydroxide. This forms a copper ammonia complex. Cupric chloride is corrosive to skin, eyes, mucous membranes and metal. Cupric chloride is used to etch copper from printed circuit boards.
Reactivity ProfileCUPRIC CHLORIDE has weak oxidizing or reducing powers. Redox reactions can however still occur. The majority of compounds in this class are slightly soluble or insoluble in water. If soluble in water, then the solutions are usually neither strongly acidic nor strongly basic. These compounds are not water-reactive.
Health HazardTOXIC; inhalation, ingestion or skin contact with material may cause severe injury or death. Contact with molten substance may cause severe burns to skin and eyes. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.
Fire HazardNon-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Some are oxidizers and may ignite combustibles (wood, paper, oil, clothing, etc.). Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated.
Safety ProfilePoison by intravenous and intraperitoneal routes. Experimental reproductive effects. Mutation data reported. See also COPPER COMPOUNDS and CHLORIDES. Can react violently with K and Na. When heated to decomposition it emits toxic fumes of Cl-.
ShippingUN2802 Copper chloride, Hazard class: 8; Labels: 8-Corrosive material.
Purification MethodsCrystallise the chloride from hot dilute aqueous HCl (0.6mL/g) by cooling in a CaCl2-ice bath. It is dehydrated by heating on a steambath under vacuum. It is deliquescent in moist air but efflorescent in dry air. The dihydrate is emerald green but blue when free from solvent. Concentrated solutions are yellow-green in colour but are blue when free from solvent. Concentrated solutions are yellow-green and become yellow on adding conc HCl. A very dilute solution is pure blue due to Cu(H2O)42+ [Donan & Bassett J Chem Soc 81 939 1902.]. CuCl2 is very deliquescent and is soluble in MeOH or EtOH to give green crystals of Cu(ROH)2Cl2. [Glemser & Sauer in Handbook of Preparative Inorganic Chemistry (Ed. Brauer) Academic Press Vol II p 1008 1965.]
IncompatibilitiesContact with strong acids forms monovalent copper salts and toxic hydrogen chloride gas. Forms shock-sensitive and explosive compounds with potassium, sodium, sodium hypobromite, nitromethane, acetylene. Keep away from moisture and alkali metals. Attacks metals in the presence of moisture. Reacts with moist air to form cupric chloride dihydrate. May attack some metals, paints, and coatings. May be able to ignite combustible materials.
