  1. Coppersulfate has already some solouble ions. Copperoxide dont have. So the process starts under and of solouble ions.
  2. Ammonium is slightly acidic and dissolves copperoxides from the ring. Ammonia is also complex agent for copper. Coppersulfate is catalyst. It should also work without copper sulfate, but slower.
  3. Dont answer to 14 year thread. If you have some imput refer with a link and open a new thread
  4. Even you can find it else where, we discuss nothing to make explosives, poisons, chemical warfare, drugs and all the supplies to it.
  5. From SO2 only get H2SO3 sulfurous acid. Not H2SO4 sulfuric acid. This you can have easier, if you burn sulfur. S + O2 => SO2 For Sulfuric acid you need a catalyst to oxidise SO2 to SO3.
  6. It depends on the sample 39730 2,4-D, water, unfiltered, recoverable, micrograms per liter 547 2,4-Dichlorophenoxyacetic acid (2,4-D) 94-75-7 39730 2,4-D IN WHOLE WATER SAMPLE (UG/L) 15651 94-75-7 2,4-D Acetic acid, (2,4-dichlorophenoxy)- 39731 2,4-D, bed sediment, recoverable, dry weight, micrograms per kilogram 547 2,4-Dichlorophenoxyacetic acid (2,4-D) 94-75-7 39731 2,4-D IN BOTTOM DEPOSITS (UG/KG DRY SOLIDS) 15651 94-75-7 2,4-D Acetic acid, (2,4-dichlorophenoxy)- 39732 2,4-D, water, filtered, recoverable, micrograms per liter 547 2,4-Dichlorophenoxyacetic acid (2,4-D) 94-75-7 39732 2,4-D IN FILT. FRAC. OF WATER SAMPLE (UG/L) 15651 94-75-7 2,4-D Acetic acid, (2,4-dichlorophenoxy)- 39733 2,4-D, suspended sediment, recoverable, micrograms per liter 547 2,4-Dichlorophenoxyacetic acid (2,4-D) 94-75-7 39733 2,4-D IN SUSP. FRAC. OF WATER SAMPLE (UG/L) 15651 94-75-7 2,4-D Acetic acid, (2,4-dichlorophenoxy)-
  7. Are you kidding? https://www.scientificamerican.com/article/see-the-highest-resolution-atomic-image-ever-captured/
  8. The compounds are mentioned. But the recipe, the supplier will not tell. The SDS is only a hint what is in. But to make it yourself will be more expensive as to buy the original. Also its a risk for safety an warranty.
  9. 1. The recycling process and its chemical and solvent makes it expensive. 2. How to avoid the oxygen. You have first an aqueous process if the iron iodide reacts with the sodium carbonate. The water contains everytime some air. How to get rid of it. 3. At alcaline conditions you have at anode an oxidation process. Iodide to iodine and hydroxide to oxygen and together forms iodate. 4. The iodine hydrogen reaction takes place at 712 K efficiently. Again a lot of energy what I needed. I think a fuel cell will not run at this temperature. 5. Its not the matter of the source of Power.
  10. Weak points. Fe2O3 + 6HI(aq) > 2FeI2 + 3H2O + I2 Note Fe3+ reduced to Fe2+ Iodine is expensive 2NaOH(aq) + CO2 > Na2CO3 + H2O Ok FeI2 + Na2CO3 > FeCO3 + 2NaI FeCO3 will be oxidised by oxygen from air back to Fe2O3. Not stable process. 2NaI(aq) + 2H2O > 2NaOH(aq) + H2 + I2 Electrolytic regeneration of NaOH This will have side reaction to NaIO3 H2O > H2 + 1/2O2 Further electrolysis of NaOH(aq) to balance H2 demand H2 + I2 <=> 2HI its equilibrium reaction at high temperature 712 K. Nothing for a fuel cell. The energy what is used produces more CO2, what you can probably absorb. PS: I corrected also some of the equations.
  11. This I didn't said. I said it is other piece of cake, but its the same cake not a separate cake. Only a piece of the whole thing. But I think we should wait for answer of Amy, if she still is interested.
  12. @Studiot This is other piece of cake, because a periodical parameter is set in, but this has nothing to do with the diffusion itself.
  13. I think she dont understand what periodical means, like at a pendelum or alterning current. Diffusion is a process where a compound penetrates through a membran or something like this. This is slowed down by this membran. There is no periodical process. The same you hit the brake of your car and its shows down. It will not accelarte by itself.
  14. What is the unit of diffusion rate? For a diffusion coefficient its cm^2* s^-1 Hertz is a unit for vibration. 1 Hz = 1 s^-1
  15. Now we should stop the discussion. We should not give receipies to make pharmaceutical products for animals and humans as well. Who will take responsibility if an animal or human gets hurt or even worse, with our suggestions to make the product.
  16. But how a amine should be removed by dilution. Lighter fuel will dissolve more hydrocarbons as polar amines.
