Identifying Gases: Tests and Results

The video tutorial explains how to identify four different gases: hydrogen, oxygen, carbon dioxide, and chlorine. For hydrogen, a burning splint is used, which causes a squeaky pop if hydrogen is present. Oxygen is tested with a glowing splint that relights in its presence. Carbon dioxide is identified by its reaction with limewater, turning it cloudy. Chlorine is detected by its ability to bleach damp litmus paper.
