A 1 GRADE COPPER SULPHATE GOST 19347-99 This reagent is one of 100 Best Quality Russian Goods of 2000Y Competition

Copper sulphate is produced from the depleted solution from electrolytic copper refining.

CuSO₄*5H₂O is water-soluble light blue or cyan hydroscopic crystals.

The copper sulphate is used for ore flotation at Coppers Concentrators, for struggle with agricultural pests, production of artificial fibers, organic dyes, mineral paints, arsenic chemicals.

Copper sulphate is referred to medium toxic insecticide-pesticide, fire-safe and non-explosive as well.
