Bluestone (otherwise - copper sulfate, copper sulfate) is a powder made up of crystals of lapis blue.In nature, it occurs in the form of a mineral.
Application
Copper - one of the trace elements needed by plants.In agriculture it is used as Bordeaux mixture (copper sulfate solution in milk of lime) of phylloxera and various fungal diseases.In addition, it has a beneficial effect on the process of respiration and photosynthesis.
Copper sulfate is also used for seed treatment before planting, destroying thus in the seeds of fungi spores.
copper sulfate (aq) was used to neutralize the effects of leakage are removed from plaster, concrete and masonry surfaces in isolating the salts, rust spots;give fireproof properties of the wood and prevent it rotting, wood impregnating solution of copper sulfate.
Anhydrous copper sulfate is used as an indicator of humidity indoors.Laboratories use it to carry out the drying of ethanol and other substances.
Copper sulfate is used in the manufacture of mineral paints, in the manufacture of cellulose acetate fibers (part of the dope).It can help you identify zinc, magnesium and manganese in stainless steel and aluminum alloys.
Copper sulphate is used in the food industry as a preservative (food additive) E519.In livestock - as mineral additives in feed.
In medicine is used as an astringent, antiseptic and cautery.In the case of white phosphorus poisoning is recommended to wash the stomach 0.1-percent solution of copper sulfate.
Copper sulfate is also used in electroplating - with copper-coated metal products;in the steel industry;a nickel plating process, and as a feedstock in the preparation of other compounds.
Bluestone: properties
Copper sulphate - non-combustible, flammable and.Very hygroscopic.It does not smell, it does not have a metallic taste.It is readily soluble in water and dilute alcohol in concentrated hydrochloric acid.When heated, it loses water and becomes gray.If after cooling drip gray powder on the water, it re-acquires a blue color.Totally dehydrated at a temperature of 258C.It melts at a temperature of 1100C.In nature comes in the form of minerals chalcanthite, butit, halkokianit and others.
crystal copper sulfate
beautiful blue crystal copper sulfate it is easy to grow at home (by the way, the same way you can grow purple crystals of hromokalievyh alum and colorless -of salt).On the whole process will take two to three weeks.For
need wire, string, a glass jar, and copper sulphate (or any other selected salt).Preparing highly concentrated salt solution: to contribute, stirring constantly, salt in a jar with water until until it stops dissolving.Then gently heat the mixture to better dissolve the salt, for which the bank (or a glass) is placed in a pan of warm water.
concentrated solution thus obtained was poured into a beaker and suspended there by means of a jumper small crystal of the same salt, on a string by immersing it in the solution.This crystallite (seed) and you want us to grow a crystal.
glass with a solution in the form of an open set in a warm place and watched as the crystal grows.When it becomes large enough, remove it from the solution were dried with a paper towel or soft cloth, cut the thread and cover it with varnish (not to "erode" in the air).
obtained crystal is very similar to the gem.
