Hello madscientists,
I want to make crystals of anhydrous sulfates (CuSO4, NiSO4,MnSO4).
My idea is to use some polar solvent (except of H2O of course) that would dissolve anhydrous solid and then by cooling of the solution or by the
evaporation process the anhydrous salt would (hopefully) crystallize. Do you know any solvent that could be suitable for this experiment? (I have
failed on searching information about solubility of these anhydrous salts in other solvents than water).
I would by very thankful for any information regarding to this topic whether it would be some tip or link to some interesting article.
Thanks in advance.

The most common method of obtaining such compounds in form of (small) crystals is crystallization from hot (~200 C) H2SO4.
See for example:
