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.

Answer:

Equipment

Apparatus

Eye protection (goggles)

Access to a fume cupboard

Protective gloves (preferably nitrile)

A length of glass tube about half a metre long with an inside diameter of about 2 cm (note 1)

Retort stands with bosses and clamps x2

Small wads of cotton wool x2

Bungs x2 (to fit into the ends of the glass tube)

Strip of universal indicator paper (optional)

Chemicals

Concentrated hydrochloric acid (CORROSIVE), a few cm3 (note 2)

880 ammonia solution (CORROSIVE, DANGEROUS FOR THE ENVIRONMENT), a few cm3 (note 2)

Acetone (FLAMMABLE), a few cm3 (optional, note 1)

Equipment notes

It is very important that the tube is clean and completely dry for this experiment. If necessary, the tube can be dried by pushing a cotton wool pad soaked in acteone through the tube and leaving it for a few minutes.

The concentrated hydrochloric acid and the 880 ammonia solution are easier to handle in small bottles than in Winchesters (large bottles) for this demonstration.
