Ammonium Chloride HCl + NH3 = NH4Cl Hydrochloric acid + ammonia hydroxide.

Easy DIY chemistry project, great for science fairs because its a great demonstration! This is great for the chemistry beginner.
I used 150ml of a 10% ammonia solution
and 50ml of 30% HCl

After they reacted, i boiled it down, and dried it in the oven. It tastes very salty/tart!
