Well see i used to do electroplating for 3-4 years and vaguely remember the zinc balls gaining a black soot type passavate over them that prevented them from breaking down any further into the KOH solution, we would either up the KOH levels or bring the zinc cages out, dip them in the HCl and then once cleaned of the crap, they would be rinsed and back in they went
My knowledge of nanoparticles is almost nonexistant except for a couple of things.
Would the nano particles just be more copper though? and if that were the case the anode should still dissolve into the solution no as its still copper?
The black soot is the only soot there, them other colours are just the end dried CuO, so i have a red, orange and brown CuO and the black is what mad the orange process turn brown so it makes me thing contaminates or some sort aha
Ive seen the the copper in the solution accumulating on the cathode which is something im used to with electroplating just not on such a thickness but i just knock it off back into the solution to be processed.
Hydrogen is definitely being created as i know that lung closing smell anywhere, not to much of the Na bath but the KOH bath i have just started it releasing Hydrogen like all sh1t which is again something id expect
Im fully aware there are quiet a few reactions going on in there with Na, Cl, H, O and Cu, just trying to figure out if the process is the same where it is going wrong and going black, which going off so far im thinking lack of Na in the Solution is causing the black soot as i had seen it a few times on the zinc cages at work when low on KOH would would either top up with more KOH or drop the zinc cages in the HCl for a minute or 2 to clean them up nice then rinse and back into the tanks and that black soot also used to make it almost impossible to break the metal down further
So a red, orange and a brown CuO are the same just different sizes? I mean i dont know but going off how these colours came about i just dont see that being the case as the brown CuO was actually Orange until the black soot stuffed the anode up and then leached into the solution causing it to go black and turned the orange CuO brown once rinsed and processed.
Trying to make CuO but worse comes to worse i believe CU2O will suffice
Would an electron microscope be what im after if trying to solve this sh1t myself?
Thanks mate
