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.
If you want to test for oxygen content of the air in a room or something like that, there are sensors that will read the percent of oxygen to determine if it is safe to enter an area. About any factory that has "confined spaces" will have a tester for this purpose. The one we use also tests for explosive/flamable vapors and carbon monoxide.
The standard test for oxygen is that it relight a glowing splint.
Yes, there definitely is a product designed to test nicotine in the air.
FADH2 I'm working on the same test!
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.

No . It does not.
Sodium is readily oxidized by oxygen gas. If the product of the reaction were dissolved in water, the color of the litmus for a litmus test would be blue. The red litmus paper will turn blue.
oxygen tanks expire because they are to be subjected to pressure test once every 5 years by a licensed pressure testing company. some companies would require their oxygen bottles to be refilled every three years. meaning your oxygen bottle is valid for three years from the date the pressure test was made, then you will refill the bottle and then the oxygen content will expire in two years, just in time for the next pressure test.
To ensure content validity of a test, you should align the test questions with the learning objectives, include a representative sample of content, and have subject matter experts review the test for accuracy and relevance to the subject matter. Conducting a pilot test can also help in evaluating the clarity and appropriateness of the test items.

Place a glowing splint into the test tube. If the glowing splint relights, then oxygen is present, otherwise oxygen is not present.
