Hi all !!
It's my second post (the first was in topic Welcome In!! :mrgreen: ). I have been reading diferent posts since I registered on the forum and also the 3 e-books (not ended yet...) that many people strongly recommended to all newbies. I also have seen the Lazersteve videos (Amazing the volume of information in them. It was a bit difficult to me to understand everything , but I understand the main ideas). I decided to use the methods of HCl/Peroxide to dissolve base metals and HCl/Clorox to refine gold because it's a bit difficult find nitric or sulphuric acid and they are expensive than normal HCl.
Yesterday, I put 70 g. of pins from different motherboards in a soak of 100 ml of HCl (20%) and 50 ml Peroxide (3%, added at little increments) to start practicing all I read. At first my solution acquired a light green yellowish color and many bubbles appeared on the surface of the pins, but after a couple hours bubbles dissapear and the color becames paler. A few minutes later all the sollution turns absolutely transparent. I added a few drops of peroxide and it becomes light green/emerald but a couple hours later the solution turns clear once again.
what's happen? I do something wrong? Too much acid in solution? Need to bubble air thru the solution? CuCl in solution instead CuCl2?
Sorry, I know they are many questions.
Tanks to all!!
Mike
