So in another thread I mentioned I met someone willing to show me some things and give some knowledge of how he refined cats but he does them AR and I’m doing it with HCl bleach. I had a batch of pgm blacks dissolving in HCl bleach and kept adding bleach and I have a reddish brown precipitate in the bottom vessel and and at first I thought it was just what happens when you put too much bleach in but it’s a whiteish color and this is a reddish brown. I don’t see how it couldn’t be palladium since palladium precipitates when introduced to chlorine gas but I’m unsure? Has anyone had this problem before?
