Simple Chemical Tests for Gases

The video tutorial explains how to test for various gases: hydrogen, oxygen, carbon dioxide, chlorine, and ammonia. Each gas has a specific test: hydrogen ignites with a squeaky pop, oxygen reignites a glowing splint, carbon dioxide turns lime water cloudy, chlorine turns blue litmus paper red before bleaching it, and ammonia turns red litmus paper blue. These tests help identify colorless and odorless gases quickly and easily.
