Some cotton wool soaked in ammonia solution was placed at the other end. the hydrochloric acid end of the tube than the ammonia solution end.
Some cotton wool soaked in hydrochloric acid was placed at one end of a glass tube.
when they meet to form a white solid called ammonium chloride.
Hydrochloric acid produces a gas. So does ammonia solution. These two gases react
What is the name of the process by which the gases move along the tube?
b Explain how this process takes place.
The particles of hydrochloric acid have a greater mass than the particles
of ammonia. Suggest why the ammonium chloride is formed nearer to
warm place.
