    In alcaline conditions also the imid group will be destroyed.

    Fundamental question on acids/bases

    If you look from outside the electrical charges are neutral, because every H+ is neutralized by a Cl-. The reaction what is going on is solvation with the water, were H2O attract H+ to a H3O+.

    CrO4 stability in aqueous NaCl?

    Chromate only dissolved by acidic solutions or rduction compounds. NaCl alone is not able to do it.

    Cobalt

    Co(NH3)62+ => Co(NH3)63+ + e- Oxidation H2O2 + 2 e- => 2 OH- Reduktion
  5. On safe side take a electrical fireplace.
  6. Then you need a lot of that stuff, the business card should be wet and the guy who hand it over had to wear gloves.
  7. Wrong. Copper is already Tetra aquo complex slight blue colour First is [Cu(H2O)4]SO4 + 2 NH3 => Cu(OH)2 + (NH4)2SO4 + 2H2O Cu(OH)2 + 4 NH3 => [Cu(NH3)4(OH)2 [Cu(NH3)4](OH)2 + (NH4)2SO4 => (Ethanol) [Cu(NH3)4]SO4 + 2 NH3 + 2 H2O

    Mixture of Sodium Bicarbonate and Sodium Chloride

    That is what I meant, it is easy to separate.

    Mixture of Sodium Bicarbonate and Sodium Chloride

    A part of the solvay process it can be used to get sodium carbonate back. https://en.wikipedia.org/wiki/Solvay_process You need only some modification.

    Peace people, anyway the topic should be locked by administrator. We should not discuss any topic about to make explosives.

    Questions about E.C.A

    There is no redox reaction: Ag+ + I- => AgI, This will precipitate. The ions still existing.

    how does chlorine hexafluoride work?

    It react with hydrogen for example 2 H2 + ClF3 => HCl + 3 HF It is used as rocket fuel

    how does chlorine hexafluoride work?

    Chlorine hexaflourid is not existing. From Chlorine there are ClF, ClF3 and ClF5 existing. All are strong oxidiser chemical like the both halogene flourine and chlorine itself.
  14. It is the limit of your device and probably also the material of your quarz cuvette. It is in UV value.

    Cupric chloride

    Boil it until all water is gone. Or put it in a ball and wait some day until the water is vaporized slowly. Result you would get nice crystalls of copper chloride
