Tetraamminecopper (II) sulphate solubility
I was wondering about the solubility of Tetraamminecopper (II) sulphate in isopropanol. Ethanol is typically used to precipitate the compound out of
solution but I have much purer and more high-quality isopropanol and would like to use it instead. I could not find any information on the solubility
of the compound in isopropanol.

The coordination complex will be less soluble in isopropanol than in ethanol (almost any water-soluble ionic compound will be less soluble in
isopropanol than ethanol). However, you may find that it oils out when you add isopropanol, as the water may have a higher affinity for the complex
than the alcohol. So don't add too much of it.
Please remember: "Filtrate" is not a verb.

I have used both 91% isopropanol and acetone to precipitate this complex, acetone is superior but they both definitely work.
