is copper ii carbonate soluble in water?

Copper ii carbonate, also known as cupric carbonate or malachite green copper carbonate, is an inorganic compound with the chemical formula Cu2(OH)2CO3. It is analogous to the mineral malachite and is commonly used as a pigment.

It is soluble in cold water and alcohol, and acid soluble to form the corresponding copper salt. It is also soluble in aqueous solutions of cyanide, sodium hydroxide, ammonium salts and alkali metal carbonates to produce copper complexes.

Common Uses:

Copper carbonate is used in the production of flares, fireworks, paint pigments, solid phosphor activators, pesticides, seed treatment and as fungicides and antidotes. It is also used in electroplating, and in the manufacturing of copper compounds.


Excessive amounts of copper ii carbonate cause gastrointestinal problems, including acute gastroenteritis, with the hydrogen-sulfur reaction playing an important role. Symptoms include vomiting of 0.20.5 g for oral administration and l 2 g for inhalation, accompanied by nervous system dysfunction, liver and kidney dysfunction, nasal septum ulcer and perforation, facial skin, hair and conjunctiva turn light yellow-green or light black-green, and dust or solution may irritate the eyes and mucous membranes.

Chronic poisoning develops in the long term. In a study on six large white pigs fed on maize meal diets with 600 ppm basic cupric carbonate for 48 days, the animals showed gradual depletion of body weight gain, depression in serum GOT, GPT and LDH activities, and loss of hepatic and renal function. In addition, the pigs in the fish-meal group showed significant signs of toxicity.
