Copper belongs to the group of the seven metals known to man since ancient times.Today, not only copper, but its compounds are widely used in different branches of industry, agriculture, medicine and everyday life.
most important salt of copper - copper sulfate.The formula of this substance - CuSO4.It is a strong electrolyte and is a fine white crystals, soluble in water, odorless and tasteless.The material is fireproof and non-flammable, with his hand completely eliminate the possibility of spontaneous combustion.Copper sulphate when exposed to even the slightest amount of moisture from the air takes on the characteristic blue color with a bright blue.In this case, there is a transformation in the blue copper sulphate pentahydrate CuSO4 · 5H2O, known as bluestone.
In industry Copper sulfate can be obtained in several ways.One of the most common - is the dissolution of copper in the wastes of dilute hydrochloric acid.Under laboratory conditions, using a neutralization reaction of sulfuric acid, copper hydroxide, copper sulfate is prepared.The formula of the following: Cu (OH) 2 + H2SO4 → CuSO4 + H2O.
property to change the color of copper sulfate is used to detect the presence of moisture in organic liquids.With the help of in vitro produce dehydrated ethanol and other substances.
widely used in the fields of agriculture bluestone or otherwise copper sulfate.Its use is primarily consists in the use of weak liquor for spraying plants and crops prior to sowing etching to destroy harmful fungi spores.On the basis of copper sulphate made famous Bordeaux mixture and lime milk sold through retail outlets and for the treatment of plants against fungal diseases and the destruction of phylloxera.
often used in the construction of copper sulfate.Its use in this area is to neutralize leakage elimination rusty spots.Also, a substance used to remove salt from brick, concrete or proshtukaturennyh surfaces.In addition, it is treated as a wood preservative to prevent decay processes.
The official medicine copper sulfate - a drug.His doctor prescribed for external application as eye drops, solutions for lavages and douches as well as for the treatment of burns, obtained by phosphorus.As internal means, it is used for gastric irritation to induce vomiting if necessary.
addition of copper sulfate produced mineral paints, it is applied to the spinning solution for the manufacture of cellulose acetate fibers.
In food industry copper sulfate is registered as a food additive E519, used as a preservative and a preservative paint.
Upon the sale of copper sulphate in the retail network of its mark as a highly dangerous substance.When injected into the human digestive system in an amount of from 8 to 30 grams of it can be lethal.Therefore, when using copper sulphate in the home should be very careful.In case of contact with skin or eyes, wash thoroughly with this place is cool running water.If swallowed, it is necessary to make washing of a weak solution of potassium permanganate, to drink saline laxative and diuretic.
