Copper Sulfate

Keywords: copper, sulfate, single salt, inorganic

Hydrated cupric salt of sulfuric acid, with formula: CuSO₄·5H₂O. Its traditional name is blue vitriol.

One of the classic compounds for crystal growing. Everybody has tried it, so no much information here.

Properties

• Crystal system: triclinic
• Crystal shape: complex prism with multiple facets
• Color: blue
• Stability on air: in my comditions it is stable, but some people report that it can dehydrate.

Growing

Usual evaporation method used. Some also note that addition of glycerol to the mother solution improves crystal clarity and makes them flattened, but I failed to grow crystals of acceptable quality this way.

Safety

Copper salts are toxic.
