6.9 Preparation of hydrogen chloride gas

From our recent discussion (Section 6.4), we know at least one method by which we can obtain hydrogen chloride gas (HCl(g)).

Questions 6.9

1. Describe one method of obtaining hydrogen chloride gas from chlorine gas.
2. Identify the two ions that can combine to form hydrogen chloride gas (HCl(g)).
3. Suggest two possible general sources of the ions identified in Question 2.
4. How can we obtain the ions in very small quantities of water so that much of the gas produced is evolved and collected rather than dissolve in it?

5. Suggest two specific sources of the ions that can be used to produce hydrogen chloride gas (HCl(g)).
6. Write an equation for the reaction between the two specific sources of the ions to produce hydrogen chloride gas (HCl(g)).
7. Suggest with a reason how hydrogen chloride gas can be dried.
8. Determine the suitable method of collecting hydrogen chloride gas (HCl(g)). (H = 1; Cl = 35.5; N = 14; O = 16.)
9. Explain why ammonium salts are not suitable for preparing hydrogen chloride gas.
10. Draw the set-up you would use to prepare hydrogen chloride gas in the laboratory.

A suitable alternative to sodium chloride is rock salt (crude sodium chloride)
