Wait until you're back at the lab in front of the fume hood. Note the white clouds of ammonium chloride that form. 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. The material that diffuses could be a solid, liquid or gas. However, this is also a good example of an irreversible gas phase acid-base neutralization. the two flasks should be about 25 cm apart on a small cart, immediately invert the aquarium over the flasks, a white cloud of begins to form over the flask containing HCl.
