Soak a ball of cotton wool in aqueous ammonia and insert a few centimetres into the glass tube. Do not remove the aquarium to replace the stoppers until you are either outside or in front of a fume hood. There are four ideas that support the particulate theory, however, two of them apply directly to this experiment. Visit us on Facebook It has to do with certain uncompromisable variables, such as the thickness of the molecule, state of which the molecule is in, and the permeability of the area into which it is diffusing. This way, we can ensure we achieve the best and safest results, as well as the most authentic discussion of their meaning. However, this is also a good example of an irreversible gas phase acid-base neutralization. When testing the effect of molecular weight on diffusion using hydrochloric acid and ammonia molecules at different ends of a sealed tube, the ammonium chloride formed when the molecules diffused towards each other and met would be closer to the hydrochloric acid end of the tube.The correct answer is, therefore, false. Avoid breathing the vapors.
