ES – Section 3 – (a), (l), (m), (q) Finally, atom economy is introduced through the manufacture of hydrogen chloride and other hydrogen halides. The Deacon process for making HCl provides an opportunity to expand on ideas relating to the position of equilibrium. 4 hours Demonstrate the reactions of concentrated sulfuric acid on sodium chloride, bromide and iodide to produce hydrogen halides. Reaction of these gases with ammonia demonstrates their acidic nature. Their thermal stability with a red-hot glass rod can also be demonstrated.
