In order to avoid the precipitation of copper (I) salts when reducing copper (II) solutions, I think you can just add ammonia, which will ensure that
Cu+ stays in solution as Cu(NH3)2+. |
Thanks, I'll try adding a little ammonia and see what it looks like for another trial.
I thought that you could precipitate copper powder from almost any copper salt solution by adding any of the following: iron, zinc, aluminum or
magnesium and I'm pretty sure I've done that before certainly with iron but also I think Al. . I know I did this with old nails but maybe it was
copper sulfate, so IDK if sulfate works differently than chlorides. the problem with the nails was the copper would coat the nails to a fair
thickness and ome would come off as a shell of he nail body, it was really odd. I'm going othave o try ,this again with different salts.
