What is Copper (II) Chloride?

CuCl2 is an inorganic compound through chemical name Copper (II) chloride.

You are watching: What is the correct name for the compound, cucl2?

Copper (II) chloride is likewise called Cupric chloride, or Copper dichloride, or Cupric dichloride. Copper dichloride occurs normally as one anhydrous mineral called tolbachite and also dehydrated eriochalcite. Both space mostly acquired from fumaroles areas.

Cupric chloride, in its anhydrous form, shows up as a yellowish-brown flour whereas in that is dihydrate form it appears as a green crystalline solid. The is corrosive to aluminium and the oxidation state the the metal is +2. That is widely provided in printing, dyeing, as a wood preservative and also in fungicides.

Copper (II) Chloride structure – CuCl2


The specific mass and the monoisotopic fixed of Cupric chloride is 132.867 g/mol. The number of hydrogen link acceptors amounts to to zero and the number of hydrogen shortcut donors equates to to zero. This compound is canonicalized and has one covalently external inspection unit.

CuCl2 supplies (Copper (II) Chloride)

Copper (II) chloride is supplied as deodorizing in the petroleum industry.Used as an oxidizing agent.Used together a purifying agent.Used as mordant in dyeing.Used as a disinfectant.Used in water treatment.Used in the manufacturing of farming chemicals.Used together a fixer in photography.Used in laundry marking inks.Used in electrotype baths.

Production that Copper (II) Chloride

Cupric dichloride is commercially acquired by chlorination that copper:

Cu + Cl2 + 2 H2O → CuCl2 (H2O)2

Health hazards:

Inhaling cupric dichloride causes sneezing and also coughing. Swallowing it reasons vomiting and pain. Once liquid come in contact with eyes and also skin, it reasons irritation in eyes and on the skin. That is non-combustible but when heated, that liberates irritating hydrogen chloride gas.


Copper (II) chloride is supplied as a catalyst because that organic and also inorganic reactions, textile dyeing and printing mordant, glass and ceramic pigment, hardwood preservative, disinfectant, insecticide, fungicide, and also herbicide, and also as a catalyst because that hydrogen chlorine processing.


Copper chloride, once breathed in, will influence you. Touch can seriously irritate and also burn with potential damages to the eyes and skin. Recurring exposure can reason skin to thicken. Copper chloride breathing have the right to irritate the nose, throat, and lungs which reason coughing and wheezing.


Copper(II) is the chemical compound that includes the chemistry formula CuCl2. The is a light brown solid, gradually absorbing moisture to form a green-blue dihydrate.


As the electrons pass from the t2 energy level to the e energy level, photons that have actually the wavelength of yellow irradiate are took in so that hydrated copper chloride i do not care violet.


For copper chloride the copper fee is 1. This forms either CuCl or CuCl2 together the copper binds to chlorine. In the instance of CuCl, the chloride ion has a charge of -1, for this reason to make the compound stable the copper must have actually a charge of +1. Therefore, copper(I) chloride is dubbed CuCl.
