A common lab procedure taught in my chemistry classes in grammar school was to perform a "splint" test. To test for the presence of oxygen, you would light the end of a wooden splint and reduce the flame to the point that the end of the splint is simply glowing red but not burning. Insert the glowing end into the unknown gas's container and observe what happens. If the flame returns, the gas is oxygen. by Ronan Lavery

There are a few ways you can remove the oxygen from a test tube. You can flick the side of it until the bubble surface for example.
A smouldering piece of wood (like a bamboo skewer) will reignite in the presence of pure oxygen.
No. Nitrogen is triply bonded, and is much more stable at "standard" temperatures than the more electronegative oxygen is.
the test of metal hydroxide is metal + oxygen = metal hydroxide + hydrogen
The standard test for oxygen is that it relight a glowing splint.
California standard test
This is a simple test that uses a specific chemical to react to the presence of oxygen in the water. An indicator is often added as well, so that depending on the level of oxygen there is a color change that can be measured against a standard reading chart provided with the test kit. You can purchase these kits at most pool stores.
Place a glowing splint into the test tube. If the glowing splint relights, then oxygen is present, otherwise oxygen is not present.

The standard test is a 3 hour GTT (glucose tolerance test).
dissolved oxygen is dissolved oxygen
You can test for oxygen by placing a glowing splint (not lit but not out) into the test tube where you think oxygen is present. If the splint relights, that means that it is oxygen. If this doesn't happen, then in your case it will be nitrogen.

What do you mean? To test for oxygen being produced, light a splint, blow it out then put it over the object you beleve is producing oxygen and if the splint re-lights oxygen is being produced.
To test oxygen content in a canned product, you should use an oxygen absorber packet. This can tell you (not exact) how much oxygen is in something, like a package.
Carbon is taken as a standard. It replaced oxygen in 1961.
