Ammonium bromide can be prepared by the direct action of hydrogen bromide on ammonia.
- NH3 + HBr → NH4Br
Now consider the following experiment. A 5 ft tube filled with Kr at 1.0 atm with the ends covered with a rubber stopper.
NH3 and HBr were then simultaneously introduced at opposite ends of the tube. A ring of solid forms where the gases meet due to the mentioned reaction.
Approximately where in the tube would you expect the ring to form?
