Principle

Gay-Lussac’s law of volumes states that gases always react with one another in certain fixed ratios of their volume.
This experiment mixes hydrogen and oxygen in the plunger eudiometer in different ratios where the mixtures react explosively. All of these gas mixtures can be ignited within a very short period of time, demonstrating that hydrogen and oxygen always react with one another in a volumetric ratio of 2 to 1.

Tasks

Examine the volume relationship in the hydrogen/oxygen reaction using a plunger eudiometer.
