Making Copper Sulfate Crystals
Copper sulfate crystals are vivid blue diamond shaped crystals.
When water is present in a sample of
copper
(II)
sulfate
it turns
blue
.
Copper sulfate crystals are actually crystals of copper sulfate pentahydrate (5 water molecules). The compound incorporates water into its structure.
Method
First identify your solute and solvent.
Solute - copper sulfate
Solvent - water
Make a saturated solution by adding and stirring copper sulfate into very hot water until no more will dissolve.
Pour the solution into a jar containing a piece of string hanging out over the edge and wait a few days for crystals to grow.
