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, resulting in a squeaky pop if present. Oxygen is tested with a glowing splint that relights. Carbon dioxide is identified by its reaction with lime water, turning it cloudy. Chlorine is detected by bleaching damp litmus paper. Each test is demonstrated with explanations of the expected results.
