The method used to collect a particular gas depends on
1) Is the gas more or less dense than
air?
2) Is the gas soluble in water?
All gases can be collected using a gas syringe.
If a gas is less
dense than air it can be collected
by upward delivery.
If a gas is more
dense than air it can be collected
by downward
delivery.
If a gas is not
soluble (or only slightly soluble) in water
it can be collected over water.
When a gas has been collected it can be tested.
