Question

With the aid diagram,decsribe an experiment which shows that Hydrogen chloride diffuses at a slower rate than ammonia

Answer 1

Answer:

Place concentrated ammonia solution on a pad in one end of a tube and concentrated hydrochloric acid on a pad at the other and watch as the two gases diffuse far enough to meet and form a ring of solid ammonium chloride

This demonstration is best performed in a fume cupboard. A black background, such as a sheet of black sugar paper, behind the demonstration helps the white ring to be seen more clearly. Actually performing the demonstration takes only a few minutes.
