Carbon dioxide – the greenhouse gas from combustion processes

Breath or room air fumes are blown through a solution of calcium hydroxide to demonstrate the carbon dioxide content.

Information and ideas:
• Observe the safety information in the related “Carbon dioxide – the greenhouse gas from combustion processes (teacher information)” teaching method, which is available on the media portal of the Siemens Stiftung, as well as the applicable safety guidelines for your school and discuss them with your students.
• Depending on the equipment and time available, the test can be carried out as a qualitative freehand experiment or on a fully quantitative basis in the specialist chemistry room.
• The answers to the questions in the experimentation instructions on the physical and chemical backgrounds are given in the answer sheet of the same name available on the media portal of the Siemens Stiftung.
