copper borate or tetraborate?
Posted 10 February 2011 - 03:20 AM
Here's what I've done so far. I've got a solution of copper II sulfate and mixed it with a solution of sodium borate (borax). This produces sodium sulfate in solution while copper II borate (or tetraborate?) ppt. Am I correct in this?
Is there another way of making copper II borate? (ie. boric acid and copper carbonate??)
Any help would be appreciated. thanks in advance.

As for copper(II) borate...not really sure either. But I imagine you can find a solvent that it will percipitate in. Then just find a soluble Cu(II) species and a soluble borate species. Stuff like this usually works for simple ionic salts. I think borax is a tetraborate hydrate though, don't know how far you'll get with that but it might work.

you can make it from copper hydroxide and boric acid.
There are, of course, an infinite number of possible copper compounds.
The one you have made is probably copper (II) borate rather than the teraborate.
