In the ammonia experiment the drops of copper(II) sulfate solution first . + After a couple of minutes, a white ring of ammonium chloride will form where the two gases meet. 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. _ A reducing agent.Violent reaction with oxidizers, strong acids, alkalis.Unless inhibited (100 ppm of the monomethyl ether of hydroquinone is recommended), can polymerize violently.Polymerization can be caused by elevated temperatures, peroxides, sunlight, or . As such, the observed ratio may be slightly less than that predicted in the simplistic model above the demo is perhaps best kept as a qualitative one at this level. The diffusion rates (velocities) of HCl and NH 3 gases will be compared. 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 reaction is:NH3(g) + HCl(g) ==>NH4Cl(s). A quick calculation (using Grahams law of diffusion) showed that ammonia diffused 1.47 times faster than hydrogen chloride. The concentrated hydrochloric acid and the 880 ammonia solution are easier to handle in small bottles than in Winchesters (large bottles) for this demonstration. A B C D 8 ) The stoppers are removed and an aquarium is immediately inverted over them. The ring usually forms nearer to the hydrochloric acid end of the tube because hydrogen chloride diffuses more slowly than ammonia. 1. Two Erlenmyer flasks, one containing concentrated ammonia solution and the other containing concentrated hydrochloric acid, are placed side by side. Effusion is a similar process in which gaseous species pass from a container to a vacuum through very small orifices.
