Why does oxygen relight a glowing splint

If damp blue litmus paper is used, the paper turns red then white. Tests for gases There are several different tests to detect and identify gases and the ions in compounds.

Oxygen Oxygen supports combustion. Hydrogen Hydrogen ignites in air. Carbon dioxide Carbon dioxide reacts with calcium hydroxide solution to produce a white precipitate of calcium carbonate.

Carbon dioxide in limewater. Glowing splint held in a test tube. Splint relights. Oxygen is present. Lighted splint held in a test tube.

The glowing splint test is a simple qualitative test that is commonly used to evaluate oxidizing gases. A splint is lit and left to burn for a few seconds. The flame is put out, leaving a glowing ember at the tip of the splint. This ember is brought in contact with a gas sample with an unknown oxidative, reductive or neutral nature.
