In Chemistry, a group of students have been presented with 2 test tubes. In both test tubes they observed bubbles rising up in a clear liquid. They are told that hydrogen gas has been produced in one test tube, while carbon dioxide was produced in the other. During this test they have been instructed to collect the gases from each reaction and identify them. How could the students collect and identify the hydrogen gas?

Diatomic, or two atoms per molecule, hydrogen can be isolated by electrically separating distilled water. This process is known as electrolysis and creates oxygen gas as well. It is by far the easiest and safest way to collect and store hydrogen gas
