  • strong ammonia solution from ammoniium chloride

    Updated: 2011-09-30 16:53:25
    Can I make a strong ammonia solution, say 20%, from ammonium chloride? It imagine it has to react with something to turn it alkaline. Been a long time since chemistry lessons.

  • buffer and salt removal from aqueous solutions of organic compounds

    Updated: 2011-09-30 16:10:02
    Hey, I have a compound that stays in the aqueous layer when I try to extract it from the reaction mixture (ethyl acetate or CHCl3-IPA 3:1); the reaction takes place in Na2HPO4/NaOH buffer. I´ve tried to precipitate it from water using acetic acid but although I have got rid of a large amount of salts, it still contains them and also a part of the compound remains in the solution..I wonder if some kind of resin (ionic exchange) could help...Any suggestion?Oh, it has a carboxylic group and an hemiacetal group; MW around 300 Da..

    If you add a base that is stronger than ammonia (e.g. NaOH), you will generate ammonia from ammonium chloride, as well as a salt - so you can make a salty ammonia solution.NH4Cl(aq) + NaOH(aq) NH3(aq) + H2O(l) + NaCl(aq)
