Symptoms of systemic copper poisoning may include: capillary damage, headache, cold
sweat, weak pulse, and kidney and liver damage, central nervous system excitation
followed by depression, jaundice, convulsions, paralysis, and coma. Death may occur from
shock or renal failure. Chronic copper poisoning is typified by hepatic cirrhosis, brain
damage and demyelination, kidney defects, and copper deposition in the cornea as
exemplified by humans with Wilson's disease. It has also been reported that copper
poisoning has lead to hemolytic anemia and accelerates arteriosclerosis., Cough, Shortness
of breath, Headache, Nausea, Vomiting, Gastrointestinal disturbance, Blood disorders, Liver
injury may occur., Damage to the lungs.
To the best of our knowledge, the chemical, physical, and toxicological properties have not been thoroughly investigated.

About Copper(II) Acetate Monohydrate

Acetate Formula Structure Copper(II) Acetate Monohydrate is odorless and efflorescent. It is soluble in alcohol and slightly soluble in ether and glycerol. Copper acetate has many applications, including as a fungicide, insecticide, Ultra High Purity (99.999%) Copper (Cu) Acetatecatalyst for organic reactions, as well as applications in electrolysis and electroplating. It is generally immediately available in most volumes. All metallic acetates are inorganic salts containing a metal cation and the acetate anion, a univalent (-1 charge) polyatomic ion composed of two carbon atoms ionically bound to three hydrogen and two oxygen atoms (Symbol: CH3COO) for a total formula weight of 59.05. Acetates are excellent precursors for production of ultra high purity compounds, catalysts, and nanoscale materials. We also produce Copper Acetate Solution. American Elements produces to many standard grades when applicable, including Mil Spec (military grade); ACS, Reagent and Technical Grade; Food, Agricultural and Pharmaceutical Grade; Optical Grade, USP and EP/BP (European Pharmacopoeia/British Pharmacopoeia) and follows applicable ASTM testing standards. Typical and custom packaging is available. Additional technical, research and safety (MSDS) information is available as is a Reference Calculator for converting relevant units of measurement.

See more Copper products. Copper Bohr Model Copper (atomic symbol: Cu, atomic number: 29) is a Block D, Group 11, Period 4 element with an atomic weight of 63.546. The number of electrons in each of copper's shells is 2, 8, 18, 1 and its electron configuration is [Ar] 3d10 4s1. The copper atom has a radius of 128 pm and a Van der Waals radius of 186 pm. Copper was first discovered by Early Man prior to 9000 BC. In its elemental form, copper has a red-orange metallic luster appearance. Of all pure metals, only silver Elemental Copperhas a higher electrical conductivity.The origin of the word copper comes from the Latin word 'cuprium' which translates as "metal of Cyprus." Cyprus, a Mediterranean island, was known as an ancient source of mined copper.
