  1. Ammonia is a gas at standard conditions, we cannot speak it has an pH, like water steam has no one. But liquid ammonia has also its autopotolysis like water it has. 2 NH3 => NH4+ + NH2- 2H2O => H3O+ + OH- So could have a pH scale based on ammonium theoretical.
  2. Its the opposit which I reduced an alkane to an alkyne. You reduce the alkyne to the Alkane.
  3. Why do you think it will not stop. If it works it will go through, even you have only two equivalent. Then some reactant will be left.
  4. If so why should it stop at acetophenon, this could react to 2 Phenyl-2-propanol. But it doesn't happen. If you use instead of the acid the ester then its possible.
  5. Carbonic acids cannot be treated with Grignard https://upload.wikimedia.org/wikipedia/commons/thumb/5/53/Grignard_with_carbonyl.png/450px-Grignard_with_carbonyl.png You can see they also treated CO2 to make carbonic acid. This would be not possible if carbonic acid would under go Grignard.
  6. Normaly its stable if you convert amines to the amid like acetamid. https://www.reddit.com/media?url=https%3A%2F%2Fi.redd.it%2F3jehma6dqs2a1.jpg&rdt=60302
  7. Ok Beside of neutrons, the other make it not radioactive, but it harm in other way as can read here. https://hps.org/publicinformation/ate/q13412.html
  8. If so then would be radiation no problem. Why the people afraid of nuclear power then. My expierence is: a cupboard in the lab got radiation where a container of K40 chloride was stored. It emittes gamma, beta - and beta+. What is your explanation for it. Why the people in Japan afraid to get the Tritium water from Fukoshima into the sea?
  9. I referred to the initial question, if material is exposed to alpha, beta or gamma rays . Nothing more, if it was unclear then I say sorry.
  10. Did I said something different.
  11. All material itself get radioactive, if exposed longer time to any of radiation. So there will be no steady material, metals and others.
  12. First this is not inorganic and second you asked it already in an other forum. We dont discuss to make pharmaceutical products.
  13. My question is what is CrO3Cl-, I know CrO2Cl2 and CrO42- or Cr2O7 2-. Or is it a mixture of NaCl and CrO3?
  14. Do an Analyse of it. Dissolve in acid and use alizarin.
  15. Can try with lower molar weight. But your acid is liquid. Can dissolve it.
  16. C is more acidic, why is it so. Check - I and / or - M Effect.
  17. R-CO-R' Keto, RCOOR' Ester But I suggestion to get a book of organic chemistry or use the WEB. Acidic will be the H close to them. The CH2 between the two Keto groups in c will be acidic
  18. Acid group COOH high acidic, followed by ketogroups, ester and alcohol
  19. Coppersulfate has already some solouble ions. Copperoxide dont have. So the process starts under and of solouble ions.
  20. 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.
