Copper sulphate - copper sulfate, CAS 7758-99-8, EC: 231-847-6, CuSO4. 5H2O,> 96%
Quality specification, parameters:
Cu content of min. 23.5%
Fe: 0.2% max
Copper sulfate (CuSO4), known under the trivial name of blue vitriol, previously as blue vitriol, is the most common compound of copper. In the anhydrous state is a white powder that receiving water blue. Therefore, it is used for the identification of water in organic liquids or as desiccants.
The aqueous solution crystallizes as a pentahydrate (blue vitriol), CuSO4 · 5H2O, in deep blue, transparent crystals trojklonných that air on the surface of airing. Copper sulfate is technically important copper salts.
Use
The material for the production of mineral colors
Impregnation of wood against rot
Canning stuffed
Seed treatment
Bordoská Jicha (a mixture of copper sulphate solution and lime milk) - a means to control pests of crops
Control of algae in swimming pools
Removing moss from roofs
Part poměďovacích spa
Staining of skin
Astringent, emetic, and etching in Medicine
Not for internal use, not to drink! When skin contact with aqueous CuSO4 wash skin with soap and water.
For your information: How to create copper sulfate crystals - instructions
First Make a saturated solution of copper sulfate:
Warm water to about 50 degrees Celsius and in it dissolve the blue vitriol until the stops dissolving (temperature maintained at 50 degrees Celsius).
Second When you cease to melt, pour the solution into another container and allow to cool spontaneously (the longer the solution to cool, the better). When cooling the crystals begin to emerge. Once the solution has cooled to ambient temperature, have a few days in peace. The solution will boil water and the crystals will continue to grow.
Third If any crystals are too small, repeat the process, but the initial temperature at which you dissolve vitriol, reduce to 30, maximum 40 degrees Celsius. Maybe even less - so it will take longer to grow crystals by evaporation. For crystal growth should be supersaturated solution and time. (Supersaturated solution occurs in the first part in the second cooling and evaporation. By cools, there is a supersaturated solution and the crystals begin to fall, further evaporation of the solution přesycuje.)
The largest crystals grow in the process of evaporation. The longer the evaporation phase, the better for the size of the crystal.
If you choose the initial temperature of saturation is high, there is a rapid cooling and supersaturation created a large number of small crystals. If this happens, the initial temperature should be reduced (see above).
Our tip: interesting shapes you can achieve if you put in a solution of a small stone or other object on which you want to root, crystals, or immersed in a solution of string tied to a pencil, which lies across the upper edge of the glass.
Hazard: harmful, irritating to skin and eyes, long-term toxicity to aquatic organisms
H302 Harmful if swallowed.
H315 Causes skin irritation.
H319 Causes severe eye irritation.
H410 Very toxic to aquatic life with long lasting effects.
