Hi All-
We are processing some PCBs, and after doing the AP method, we dissolved the filtered/rinsed foils in Acid/Clorox. I expected a yellow-green color, based on what I'd seen on the forum here, but instead I got this deep red.
I did a search, and from what I understand, this is fine (and maybe even good?).
We precipitated the gold, and it's a very, very fine black powder. We have yet to melt or anything. Just wanted a sanity check to make sure the color of the solution prior to dropping looked okay![Wink ;) ;)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
