Question:

How can you get pure (Lab Standard) Ammonia, from House-Hold Ammonia?

Another part of the school project requires a little more skill, I need to get pure-ish Ammonia to help produce Ammonium Hydroxide (or Ammonia in water) from an ammonia cleaner. Help =[

  1. There is no way this is a school project. Maybe at university (or college in the US), done in a controlled environment when the students are told what they are doing and have access to fume cupboards.


  2. You have a school project and so I presume any dangers to you have been explained. On this basis I should just explain that a standard method of determining Ammonia content is to add sodium hydroxide so that the reaction is that NH3(gas) is driven from the ammonium salt(or hydroxide:a REPLACEMENT REACTION).If you are trying to determine the concentration of ammonia base then you use a known quantity of the NaOH(in excess),boil the mixture in a fume cupboard to drive off the freed ammonia,then titrate the NaOH solution.So what you need to do is to add excess NaOH to you ammonia source in a flask and heat:you should collect the evolved ammonia (probably by passing it into ice- cold water to make an ammonium hydroxide solution).It is not too difficult to liquify the ammonia gas but I really think that might present to much danger to you.Good Luck!P.S Dont get too scared by all that danger nonsense,ammonia gas is the effective ingedient in old fashioned smelling salts,BUT you will find that a hooter or peeper full will be uncomfortable and thats about as bad as it gets; unless you are a real nutter!

  3. i would help you but i got a u in chemistry...sorry =)

  4. No.  And its dangerous.  Ammonia is a toxic corrosive gas.  And ammonium hydroxide is a highly corrosive base.  

    You wouldn't get high purity anyway so don't even try it.  Reagent grade ammonium hydroxide can't be produced in your kitchen.

    Sounds more like you are up to no good.  No teacher would assign something that dangerous and stupid.

    LD, read more carefully.  This kid is looking for a source of reagent grade ammonium hydroxide.  Process will be done in his kitchen.  Read the previous question in his profile.  My bet is that this is not for school but some illicit procedure found on the web.  Producing ammonia gas in your kitchen IS DANGEROUS.  What school chemistry lab would not have ammonium hydroxide or send a kid looking for it on his own.  Don't be naive.
