CuSO4 + NaCl

[rucito]

Hi all
As I read this-
http://goldrefiningforum.com/phpBB3/viewtopic.php?f=37&t=2343&p=48774&hilit=CuSO4#p48774
I remembered that one of the ways to make boards ever was-CuSO4 + NaCl + heat.
I decided to try that and whether to terminate the boards.
I put a finger in the solution and put it on the hot plate and only 10 minutes longer gold flakes floating in it!

You need to wash your hands :shock:

You're link did not work, so I have no clue what thread you referenced. Can you edit the link :?:

That sounds very interesting!

Since CuSO4 dissociates in water to its ions Cu⁺⁺ and SO₄^--, the copper already has a valence of (II). Together with Cl^- it is nothing else but CuCl₂ also called AP. Can anybody confirm or correct this?

I wonder,if PbCl2 could be used to make CuCl2 from CuSO4, since PbCl2 is a little bit soluble (1-3%), while PbSO4, especially in presence of excess SO4^--, would precipitate quantitatively.

Niteliteone the link worked for me
I will paste and see if it is yhe same
If not it is called

The link is correct and working fine now.
When I first replied it was written in black and the last characters were "=CuS04...", if I remember correctly. It is fixed and working now, so all is good. 8)

Of course Cu++ is etching Cu
