The particles of hydrochloric acid have a greater mass than the particles of ammonia. suggest why the ammonia chloride is formed nearer to the hydrochloric acid end of the tube than the ammonia solution end

Answer::

The ring usually forms nearer to the hydrochloric acid end of the tube because hydrogen chloride diffuses more slowly than ammonia. This is because hydrogen chloride has almost twice the molecular weight of ammonia, and the rate of diffusion is inversely proportional to the square root of the molecular mass of the gas.','.
