  1. Hmmm... I see, thanks for the input.
  2. I've been scouring the web for some hours, looking for the temperature at which potassium carbonate decomposes into potassium oxide, but have had no luck (e.g. wikipedia only tells you that it will decompose before boiling, but not at which temperature this happens... argh). This is the best I've found: https://www.sciencedirect.com/science/article/abs/pii/S0040603198002895 Does anyone know something about the matter?
  3. https://water-research.net/index.php/water-treatment/tools/hard-water-hardness According to this source, soda ash can form insoluble precipitates with calcium and magnesium ions. Oh boy, getting pretty easy to decontaminate water.
  4. Yes, as I said, I know how to deionize water, but I'm trying to make an alternate process (as cheap as possible, trying to make just 5-10 L on each run) to produce something similar to deionized water without the ion exchange membranes. I suppose many post-filter volatilites can be eliminated simply by letting water boil for 5 or so minutes (with no distillation apparatus).
  5. I'm looking for ways of making a cheap scale (doesn't need to be too precise) and I turned to vacuums to use as a countering force (or atmospheric pressure, to be more precise). I'm thinking of simply sealing a syringe's barrel (the chamber) and then tying a little basket on the plunger (the tail), so I can weigh down the basket (with things I want to measure) and have the plunger move down to get a measurement. What do you guys think? Is the principle practical for such purpose?
  6. I use simple fabric as a separation membrane (though I think, that is only relevant when separating NaCl (or KCl, I suppose), to avoid making sodium chlorate) and conductive paint for electrodes (similar to using graphite). It totally gets rid of the carbonate (turning it into CO2) for the soda ash (I think its a very well documented reaction), why wouldn't it for the pearl ash?
  7. I've been producing some biodregradable hydrogels for some time and, one of the requisites for their manufacturing is deionized water (really, really pure water). Quality ion exchange resins can be a bit costly, so I learned how to regenerate them, though the process can be a bit problematic as well. So I ended up turning to trying to make my own process of deionization (or as close as I can get to it) to simplify my work. So I came with the following process: 1. Pass tap water through an HEPA and activated carbon filters, to get rid of small particles and VOC (volatile organic compounds). 2. Shake the water pretty hard, to eliminate some disolved gases. 3. Boil it a little bit, to eliminate low boiling point volatilites and the rest of the disolved gases (at the cost of losing a little bit of water). 4. Distill the water (as close to 100°C as possible), to rid it of solubles and high boiling point volatilites (maybe use a fractionating column?). Such process, I think, should eliminate all but the most exact of azeotropes from the water. What do you guys think?
  8. I've been doing some electrolysis experiments with soda ash (sodium carbonate) to decarbonate it and synthesize sodium hydroxide. Having recently extracted some pearl ash (potassium carbonate) from wood ash, I became curious in doing the same thing with it. Will electrolysis of potassium carbonate yield potassium hydroxide?
  9. Yes, that's what i thought. Thanks for the response.
  10. I just watched this video: Of some dude/gal making glycerine seemingly without a base/acid. It doesn't seem to me that he knows what he is doing, but maybe he does, so I wanted to ask any organic chemists, if you think he managed to separate the triglycerides with this process?
  11. yes... bad slip, i meant "stabilizer" :S And on that note (forgive my ignorance), what keeps the ammonia in your supermarket bottle from coming apart?
  12. hmmm... interesting, so the process involves, turning a rare earth (possibly iron too) into powder, then using a magnet to align all the particles (as if using electricity to make a permanent magnet) and then cooking the whole thing to nucleate it and make it grow crystals.
  13. Hmmm, I see. So the problems are heat and pressure, the former may be solved using cold plasma/ionization (using something like a tesla coil), and the latter using a catalytic to stabilize the resulting ammonia.
  14. I've become interested in being able to make magnets from scratch (without electricity), and turned to iron and iron oxides (such as hematite) to try and turn them into magnetite. Anyone knows if there's a way to do that? Or how feasible is it?
  15. I added nitrous gas, because, the hydrogen wouldn't burn in just nitrogen, would it? If the torch won't work, would an electrical arc, in a pure nitrogen (N2) and hydrogen (H2) atmosphere?
