Graham's Law: Diffusion of ammonia gas and HCl (g) Two Erlenmyer flasks, one containing concentrated ammonia solution and the other containing concentrated hydrochloric acid, are placed side by side. Since the molar mass of hydrogen chloride is about twice that of ammonia, that means that ammonia diffuses about forty percent faster than hydrogen chloride. Ammonia solution reacts with hydrochloric acid (a solution of hydrogen chloride in water) in a similar way. Any in SPE Disciplines (5) Journal. CORROSION 2008 (1) CORROSION 98 (1) SPE Improved Oil Recovery Symposium (1) Publisher. Similarly, the medium in which diffusion occurs could also be in one of the three physical states. We've encountered a problem, please try again. Add stoppers to both ends of tube Diffusion in Gases Diffusion in Gases Ammonia gas and hydrogen chloride gas are each made up of particles. Excessive secretion of the acid causes gastric ulcers, while a marked deficiency of it impairs the digestive process and is sometimes the primary cause of deficiency anemias. 2 4 6 v The hydrochloric acid-ammonia diffusion experiment shows that the heavier the gas particles are, the slower they are to diffuse. Consequently, the white ring of ammonium chloride will form much closer to hydrochloric acid end of the tube. When ammonia reacts with hydrochloric acid (above), the hydrogen from the $\ce{HCl}$ moves to the ammonia. It has the chemical composition of HCl and has two ions, the hydrogen ion and the chloride ion It is having the weight of 35.5 grams. b) Describe and explain what you see in the tube.
