Описание A set of 500g of sodium bichromate and 500g of copper sulfate in plastic buckets for the preparation of an indelible fire-bioprotective antiseptic XM-11. 1,2,3 Na2Cr2O7 Applications: In the leather and fur industry for tanning leather and furs. In the chemical industry in the production of inorganic pigments, catalysts and other chromium-containing compounds. In the textile industry when dyeing fabrics as a mordant. In a ratio of 1:1 with copper sulphate, it serves as an indelible fire-bioprotective antiseptic XM-11 for wood. The second component: Copper sulphate 500g. GOST 19347-2014. Grade A. Grade 1. Synonyms: copper sulfate five-water, copper (II) sulfate five-aqueous. CuSO4*5H2O. Mw=249.685. CAS 7758-99-8. Min 25% Cu. It has disinfectant, antiseptic, astringent properties. It is used in medicine, in crop production as an antiseptic, fungicide or copper-sulfur fertilizer. The ease of growing copper sulfate pentahydrate crystals and their sharp difference from the anhydrous form are used in school education. In mechanical engineering, it is used to paint metal parts before they are manually marked. In construction, an aqueous solution of copper sulfate is used to neutralize the effects of leaks, eliminate rust stains, and also to remove salt secretions (“efflorescence”) from brick, concrete and plastered surfaces, as well as an antiseptic and fungicidal agent to prevent wood decay. In agriculture, copper sulfate is used as an antiseptic, fungicide and copper-sulfur fertilizer. To disinfect the wounds of trees, a 1% solution (100 g per 10 l) is used, which is rubbed into previously cleaned damaged areas. Against late blight of tomatoes and potatoes, plantings are sprayed with a 0.2% solution (20 g per 10 l) at the first signs of the disease, as well as for prevention in the event of a threat of the onset of the disease (for example, in wet, humid weather). The soil is poured with a solution of copper sulfate to disinfect and make up for the lack of sulfur and copper (5 g per 10 l). However, more often copper sulphate is used as part of the Bordeaux liquid - the main copper sulfate CuSO4•3Cu(OH)2 against fungal diseases and grape phylloxera. Chemical treatment with copper sulphate is also used to combat water bloom in reservoirs. It is also used to make mineral paints, in medicine, as one of the components of electrolytic baths for copper plating, etc. and as part of spinning solutions in the production of acetate fibers. In the food industry, it is registered as a food additive E519. It is used as a color fixative and preservative. In everyday life, it is used to remove rust stains on the ceiling after flooding. At the points of buying non-ferrous metal scrap, a solution of copper sulphate is used to detect zinc, manganese and magnesium in aluminum alloys and stainless steel. When these metals are detected, red
