What gases can be collected by displacing water? Which gases should be collected by air displacement? Tell us how you can collect the following gases:
a) nitrogen,
b) ammonia,
c) hydrogen,
d) hydrogen chloride.
By displacing water, gases that are insoluble in water and do not interact with it can be collected. The air displacement method can collect almost any gas, except for gases interacting with air components.
a) water displacement and air displacement
b) air displacement, because ammonia reacts with water and is well soluble in it
c) displacement of water and air
d) by displacement of air, because hydrogen chloride is soluble in water
