Below I have included a method by which one can produce ammonia gas for use in reactions or to dissolve in distilled water to produce very pure
ammonium hydroxide. You can use different masses of reactant to produce more, or less, NH3 gas. I have used equimolar masses (0.1 moles each).
CaO+2NH4Cl--heat--->CaCl2+2NH3+2H2O
Equipment
5.6g CaO
5.3g NH4Cl
Test tube with delivery tube
Source of heat (eg. bunsen burner/gas cooker)
Method
1. Add the two reactants (calcium oxide and ammonium chloride) in the test tube.
2. Stopper and put the end of the delivery tube where appropriate for your reaction (or into distilled water to make pure ammonia solution)
3. Heat strongly, if a no gas is formed add 0.2ml of water.
4. Continue until no ammonia gas is formed.
Safety
Calcium oxide is corrosive, wear gloves and goggles when handling.
Ammonia gas is toxic and irritant.
Thank you very much for reading this post!

Beginnings please.
Nice to see a wll laid out procedure.
You can omit the safety bit on this site - they all know all about it.
Sorry, I just supposed that this post would go in the Reagents acquisition thread(can I move which thread it is on after posting ?)
Thank you for complementing my procedure. And thank you for spending the time to read my posts!
I appreciate your kindness aga - 26-7-2015 at 12:05
No, once posted you need to ask a moderator to move the thread.

Enjoy it while it lasts !
After a while you'll get all lazy and post something that a far more experienced person stamps on, and stamps it Flat.
They will be 100% correct of course, and in this way we all learn.

Very true, that is why I joined this forum; because I wish to learn.
