Read our standard guidance on generating, collecting and testing gases during practical experiments, including carbon dioxide, hydrogen, oxygen and chlorine.
Core Chemistry 14 - 16. Collecting and testing gases. This page looks at how you can collect and test samples of hydrogen, oxygen, carbon dioxide, ammonia and chlorine in the lab. It looks at four simple ways of collecting gases - over water, downward into a test tube or gas jar, upwards into a test tube or gas jar, and into a gas syringe.
This page describes a variety of methods and techniques for preparing and collecting gases - summarised details including diagrams of the apparatus, the chemicals-reagents needed, and the gas preparation reaction equations
Learn the basics about collecting and identifying gases? what are the methods and techniques used, and why is it done?
Generating, collecting and testing gases. In association with Nuffield Foundation. Read our standard guidance on generating, collecting and testing gases during practical experiments, including carbon dioxide, hydrogen, oxygen and chlorine.
Produce a potassium manganate (VII) reaction using a test tube, Bunsen burner, and scientific inquisition to detect the presence of oxygen. Includes kit list and safety instructions.
22 lut 2023 · Collection should take place via the downward displacement of water (if the gas doesn't react with water) or the downward or upward displacement of air (depending on the relative density of the gas). Gas should be collected in a balloon to be easily accessible in a lecture demonstration (see 4.1 video and 4.2 demonstration sheet and video).
