Oxygen gas relighting a glowing splint. The oxygen gas is produced by the decomposition of hydrogen peroxide, which is squirted into a test tube containing the decomposition catalyst manganese (IV) oxide. When the glowing splint is introduced to the test tube, it bursts back into flame when it contacts the oxygen.

How do glowing splints react with oxygen?

A glowing splint is held above a glass tube, in which oxygen gas is trapped. When the stopcock is opened, oxygen gas rushes out, and ignites the glowing splint.

Can oxygen relight a burning splint?

A glowing splint applied to a sample of oxygen gas will relight. The rate of reaction can be increased using a catalyst , manganese(IV) oxide.
