i mixed a solution of 10% ammonia,
with a 10% hcl solution.

funny crystals heh?
but why they have different shapes?
i mean look at the ones in the border and then a the ones at the center.
they are completely different.
anyway, if somebody knows a way to get pure ammonia out of these in a siple way.
please tell me.
respect

If you mix ammonium chloride with a strong base like NaOH, ammonia gas should evolve. I'm talking about dry salts, not solutions. If they are too
dry, a drop of water should start the reaction. From then on, it produces its own water.

the best way to ammonia
is to intimately mix absolutely DRY (ovendried) NH4Cl with CaO - quicklime - a grinder comes handy her, wearing gloves and eyeprotection is advised
and dont inhale CaO-dust - a wet cloth over nose and mouth is helpful here.
So grind together the ammoniumchloride with a good molar excess of CaO, put it in a vessel and drop some drops of strong lye onto this mixture.
Voila! NH3 almost dry! 
If you want it absolute dry you need to add a rather small drying tube filled with an NaOH/CaO mixture.

I bought a 20lb bag of ammonium sulfate for 3$ (honest!) and Imake ammonia by mixing it with NaOH in water.

Thought I'd bring this up on an existing thread rather than starting a new one.
I spotted this interesting story about a new process to convert Nitrogen to Ammonia using Zirconium in solution. No catalysts (I think, if I read the
story right), no high pressures and temperaturess less than boiling water. Apparently, the Zirconium forms a complex (with the water I guess -
they're a little vague on some of the details) then adds Hydrogen across the Nitrogen bonds using that complex. They say it's not
industrially viable but could be used to make small amounts of interesting Nitrogen compunds.

I suppose you might have to have a ready source of Zirconium, though...
