How do you test oxygen​

`\underline{ \underline{ \large{ \tt{Test \: Of \: Oxygen \: Gas}}} }:`

• To test whether the produced gas is oxygen or not , introduce a glowing matchstick in the jar containing gas. This burns with bright light. It proves that the gas in the gas jar is oxygen.

• When a burning magnesium ribbon is introduced inside the gas jar , it burns with dazzling light and produces white ash of magnesium oxide. This proves that the gas jar contains oxygen.

Answer 2

The glowing splint test is a test for an oxidizing gas, such as oxygen. In this test, a splint is lit, allowed to burn for a few seconds, then blown out by mouth or by shaking. Whilst the ember at the tip is still glowing hot, the splint is introduced to the gas sample that has been trapped in a vessel. Oxygen supports combustion so a good method of testing for oxygen is to take a glowing splint and place it in a sample of gas, if it re-ignites the gas is oxygen. This is a simple but effective test for oxygen.
