    Wow, you can really see how much copper is missing after the reaction. Looks like it took care of the thin sheets surrounding the contacts. I'll use this method to get rid of the copper before further purification. Thank you!

    Nice and simple, also heard you can dissolve copper with ammonium nitrate dissolved in water

    good job. does this solution work to clean silver/palladium relay contacts from copper?

    • @escrapchannel

      Hi, palladium will be dissolved, too. At least the surface layer, so you will have some Pd in solution.

      Hi, to be honest I never tried, but palladium is possible to be attacked in a solution of strong oxidiser like hydrogen peroxide in presence of chloride and acid. You gave me idea to test this. Thanks!

    Giving this a go now and at the moment it's fizzing away but the solution is more green (could be the brass)
    Does anyone know what the gasses are, bubbles start off big (oxygen?) and now really small (hydrogen?) would like to know if worth collecting the gas in the process 🤔

    • @escrapchannel
      @escrapchannel  21 วันที่ผ่านมา +1

      @@Andykerrfield Hi, bubbles are nitric oxides. No need to collect them. Solution can turn greenish if nickel present and dissolved or if silver contacts covered with palladium.

    Did you have silver chloride in your solution? I ended up with a good amount of it on the bottom of my beaker.

      Hi, no. In my case I did’t see silver chloride formed.
