NH3 (g) + HCl (g) NH4Cl (s) Available for both RF and RM licensing. Nigel Baldwin. This demonstration is best performed in a fume cupboard. In this demo, that means that the ammonia makes it to the hydrogen chloride flask before the hydrogen chloride has a chance to make it to the ammonia flask and we observe the reaction taking place above the HCl. The hydrochloric acid-ammonia diffusion experiment shows that the heavier the gas particles are, the slower they are to diffuse. The different sizes of the molecules and their collision cross sections with other molecules come into play. Conclusion: The reaction which is taking place is: ammonia .
