Question on the preparation of tetraaminecopper (II) sulfate crystals.
According to the resource cited below, ethyl alcohol is used to precipitate the tetraaminecopper (II) sulfate, but I have no ethanol available at the
moment. I do have isopropyl alcohol; would this be suitable? I've be trying to isolate the crystals of this compound for a while, to no avail, as it
keeps decomposing into copper hydroxide. I think this could be successful.
Thank you in advance!

If you add isopropanol to a concentrated solution of copper(II) sulphate (with or without the ammonia), you may find that you get two layers, and the
isopropanol doesn't mix. Use methanol instead, if you can get it.
Please remember: "Filtrate" is not a verb.

Are there any other substitutes? I don't quite have the funds at the moment.

Look at an auto or hardware
store for Heet antifreeze (little yellow bottle) it is basically just methanol and is really cheap.
