I have a bit of HCl sitting on top of what supposedly looked like copper oxide. After I added HCl, though, I saw that there was now a red solid, which
was copper, which was the most part of what was supposedly copper oxide. Now I have to get the HCl to react with the copper.
I was thinking about boiling off water from my very dilute 3% H2O2, but I don't have much of it, and it would also be really dangerous. So I was
hoping that maybe a few drops with most of their water boiled off would be enough to get the reaction going, but I am really not sure how rigorous the
decomposition would be if I overshot the goal. Or maybe there is an alternative to H2O2?Bedlasky - 20-4-2020 at 15:00
I think that 3% H2O2 should be fine. Mix solutions and heat it.
You can use any source of nitrate instead of H2O2.reactofurnace - 21-4-2020 at 00:14
Is your goal to make Copper (II) chloride? If so the 3% H2O2 should work just fine. You could also bubble air into the mixture, however, this might be
slow. In addition, I read on Wikipedia that the reaction of copper oxide and ammonium chloride is feasible (at temps of about 300deg celsius)Draeger - 21-4-2020 at 10:00
Yes, but do it outside, because of chlorine formation.
Is there some way I could prevent chlorine formation? I can't do it outside, and there is no well-ventilated place in my home, either.Herr Haber - 22-4-2020 at 11:31
In front of a window, remove anything metallic from the immediate surroundings, if possible blow a fan.
But I dont think you'll be producing a worrying amount of chlorine anyway. Just dont stay around in the room if you cant do it outside.lordcookies24 - 24-4-2020 at 19:32
I did this 2 years ago with 3% H₂O₂ to get CuCl₂ and it catalyzed it very well. Be sure to heat the solution well and if you have magnetic
stirrer use it. Also I did this outside and it is a good thing I did because I might have heated it up a bit too much cause when I came outside after
an hour my porch was well decorated with CuCl₂ crystals splattered all over.
