Copper(II) hydroxide has been known since copper smelting began around 5000 BCE although the alchemists were probably the first to manufacture it. This was easily done by mixing solutions of lye and blue vitriol, both chemicals which were known in antiquity.
It was produced on an industrial scale during the 17th and 18th centuries for use in pigments such as blue verditer and Bremen green. These pigments were used in ceramics and painting.
The Copper hydroxide is an organic compound with the formula Cu.(OH)2. The IUPAC name of this chemical is copper dihydroxide. With the CAS registry number 20427-59-2, it is also named as Kupfer(2+)dihydroxid. The product's category is Inorganics. Besides, it is a blue powder, which should be stored at temperature of 0 - 6 °C. It is used as raw material of copper, mordant, rayon, paint, and also used as a fungicide and anti-fouling paint composition.
Physical properties about Copper hydroxide are: (1)ACD/LogP: -1.38; (2)ACD/LogD (pH 5.5): -1.38; (3)ACD/LogD (pH 7.4): -1.38; (4)ACD/BCF (pH 5.5): 1; (5)ACD/BCF (pH 7.4): 1; (6)#H bond acceptors: 1; (7)#H bond donors: 2; (8)Polar Surface Area: 20.23 Å2; (9)Enthalpy of Vaporization: 40.65 kJ/mol; (10)Boiling Point: 100 °C at 760 mmHg; (11)Vapour Pressure: 24.5 mmHg at 25°C.
Preparation: this chemical can be prepared by Copper sulfate and sodium hydroxide. Chemical reaction equation is as follows:
CuSO4+2NaOH→Cu(OH)2+Na2SO4
