You are provided with a long glass-tube, fitting corks, cotton wool, concentrated solution hydrochloric acid and concentrated ammonia solution.
(i) Draw a possible set-up to compare the rates of diffusion of ammonia gas and hydrochloric acid gas
(ii) Outline a clear procedure on how the experiment can be carried out.
(iii) What are the possible observations and conclusion

Answers

(ii) Experiment procedure
- A long glass tube is clamped horizontally as sown in the figure below
- A piece of cotton wool is soaked n concentrated solution of hydrochloric acid and another in
concentrated ammonia solution
- Simultaneously, the soaked cotton wool pieces are inserted at the opposite ends of the horizontal
glass tube and cork.
- Observations are the noted

(iii) Possible observation.
-A white deposit of ammonium chloride forms on the walls on the walls of the glass tube in
the region nearer end B
Conclusion
- Different gases have different rates f diffusion
