copper hydroxide, compound (II) - is a bright blue crystals, may also have an amorphous (powdered) structure.It is insoluble in water, the estimation of the average registry security.The chemical formula of the substance - Cu (OH) ₂, it is a weak base, which is typically obtained as a result of exposure to strong bases copper salt.
The use of this compound is widespread in various fields of chemical and industrial production.For example, copper hydroxide used as a pigmenting component of glass, ceramics, used in the art and jewelery, glazes.Pigmentation properties of the compound have been successfully used in the manufacture of high-resistant paint used for coating the bottoms of ships and even submarines, since this substance prevents fouling of underwater parts of ships algae and other water elements spoil the metal vessels.
great prospects for the use of the substance in modern electrical and electronic industries.Here, it can become an indispensable component of the production technologies of high temperature superconductors.Further, in electrical applications already tested in laboratory practice.
property in chemical manufacturing copper hydroxide is widely used as a catalyst for chemical reactions.In addition, you can also specify and such the application area as the preparation of fodder for cattle, the production of various grades of cement, especially decorated (colored) cements.
Although security classification of the compound is not a highly toxic and hazardous chemicals, working with them is necessary to fulfill some important precautions.First of all, it refers to the adherence to the storage material and prevent it from spilling cases outdoors.If this happens, you should immediately take steps to isolate the space wastage and disposal hydroxide at a safe distance.
As the formula shows, copper hydroxide - is an alkaline compound.Therefore, all existing and future versions of its practical use, it is caused by alkaline properties.
Before answering the question of how to obtain copper hydroxide, should make a reservation that there are a number of options.
Consider some of the most common ones.
Get hydroxide, copper sulfate can be of her.This substance is soluble in water, white powder with a crystalline structure.Its chemical formula - CuSO₄.If it is a substance called copper sulfate dissolved in water, you can get a well-known copper sulfate.Then, if this alkali solution was added, the reaction occurs during which stand out and Cu (OH) ₂ as a precipitate of blue color.
hydroxide can be obtained from copper nitrate (II), which is a crystalline substance having no color, with the chemical formula Cu (NO₃) ₂.If the reaction is carried hydroxide preparation, it is necessary to add the NaOH solution of copper nitrate (II).The resulting reaction precipitate of blue color is the desired copper hydroxide.
A common method of obtaining a substance and the use of this copper chloride (II), which has the chemical formula CuCl₂.For hydroxide must yellow powder which is copper chloride dissolved in a certain amount of alkali.During this reaction yellow crystals disappear, and instead falls all the same necessary to us, and the precipitate of blue color - Cu (OH) ₂.
