Potassium bis(oxalato)Cuprate(II) Hydrate is generally immediately available in most volumes. High purity, submicron and nanopowder forms may be considered.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.
Potassium is a Block S, Group 1, Period 4 element. The number of electrons in each of Potassium's shells is 2, 8, 8, 1 and its electronic configuration is [Ar] 4s1. In its elemental form potassium's CAS number is 7440-09-7. The potassium atom has a radius of 227.2 .pm and it's Van der Waals radius is 275.pm. Potassium is not toxic. Potassium is the seventh most abundant element on earth. In its metallic form it is one of the most reactive and electropositive of all metals and rapidly oxidizes. As with other metals of the alkali group, the metal decomposes in water with the evolution of hydrogen. It catches fire spontaneously in water. In high purity, potassium compounds have numerous pharmacological, medical, and electronics applications. Important compounds include the hydroxide, nitrate, carbonate, chloride, bromide, iodide, and sulfate. Lower purity compounds are used in pyrotechnics for its violet color on ignition and in glass and ceramic glazes to produce this color. Potassium also used as a nutrient in plant growth. Potassium was first discovered by Sir Humphrey Davy in 1807. The origin of the element name comes from the English word 'potash' meaning pot ashes and the Arabic word 'qali' which means alkali. The symbol K originates from the Latin word 'kalium'. See Potassium research below.
Copper is a Block D, Group 11, Period 4 element. The number of electrons in each of Copper's shells is 2, 8, 18, 1 and its electronic configuration is [Ar] 3d10 4s1. In its elemental form copper's CAS number is 7440-50-8. The copper atom has a radius of 127.8 .pm and it's Van der Waals radius is 140.pm. Copper is an essential trace element in animals and plants, but in excess copper is toxic. Due to its high electrical conductivity, large amounts of copper are used by the electrical industry for wire. Of all pure metals, only silver has a higher electrical conductivity. Copper is also resistant to corrosion caused by moisture, making it a widely used material in pipes, coins, and jewelry. Copper is often too soft for its applications, so it is incorporated in numerous alloys. For example, brass is a copper-zinc alloy, and bronze is a copper-tin alloy. Copper sulfate (CuSO 4·H2O), also known as blue vitrol, is the most well-known copper compound. It is used as an agricultural poison, an algicide, and as a pigment for inks. Cuprous chloride (CuCl) is a powder used to absorb carbon dioxide (CO2). Copper cyanide (CuCN) is often used in electroplating applications. Copper is available as metal and compounds with purities from 99% to 99.9999% (ACS grade to ultra-high purity); metals in the form of foil, sputtering target, and rod, and compounds as submicron and nanopowder. Copper was first discovered by Early Man. 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. See Copper research below.
