A Very Special Electrode
I recently purchased a rather unique type of electrode material with some very interesting properties. This 10x10 mm piece of material is boron-doped diamond - a lab-grown diamond manufactured such that it conducts electricity at room temperature. In the video, we demonstrate some properties of a boron-doped diamond electrode, and compare it to some other materials I have on hand.

    I get it that HCl in water has an azeotrope of 20.2%... Therefore, the LIQUID output from your condensor will be at that strength. However... If you were to use 33% in your boiling flask, and you allowed your condensor output to bubble through the content of your azeotropic receiving flask *thereby re-absorbing HCl gas into the azeotrope), wouldn't you end up with something fairly close to your 33% source acid? (Industrially, 33% HCl acid is produced by absorbing HCl gas into water until it's near saturation. There's many industrial processes that release HCl gas as a 'waste' product and this waste is used to make 33% HCl)

    • @ScrapScience

      Correct. I just didn't really want to deal with trying to dissolve HCl gas in water in this case. If things went wrong or the gas were improperly absorbed, it would present a pretty big issue.

    Nice work I’m wondering if you can let it run more time to break down more water hence concentrating the acid a bit more. I realize this is proof of concept but I feel like this would even with 5 times the concentration of copper sulfate. Or, since your acid is very dilute, add more copper sulfate and repeat until the acid or 2 or 3 Molar. Oh I’d like to mention sulfuric acid reduces copper sulfate solubility it water through common ion effect (sulfate). So if you go the route of adding more copper sulfate repeating and repeating you will find a point when it’s no longer feasible to try to add copper sulfate for another run and then you have less water to boil off.

    I remember doing this over 40 years ago and used carbon rods from batteries, or maybe stainless steel rods, but I've forgotten my chemistry by now. I boiled the acid next to increase concentration. To what extent can this be done to improve concentration, because from what I remember, acids absorb water and that's the reason they are so harmful to organic matter? (I presume the stainless steel I used wasn't a good idea because of the chrome salts I made.

    • @ScrapScience
      @ScrapScience Месяц назад

      The porosity does come into it, but it's not the main reason behind the degradation. When used as an anode, a very small amount of carbon is able to be oxidised to form CO or CO2. Since these electrodes have a porous structure, this oxidation can happen inside the electrode instead of just on the surface, causing them to disintegrate. Without any oxidation, no disintegration occurs. Likewise, making the electrodes less porous (i.e. HOPG electrodes) leads to much less electrode damage (but not zero).
