what is the best testing kit to use to detect cocaine
The standard test for oxygen is that it relight a glowing splint.
Place a glowing splint into the test tube. If the glowing splint relights, then oxygen is present, otherwise oxygen is not present.
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.
dissolved oxygen is dissolved oxygen
The glowing splint 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.
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 put a lit match in a test tube of oxygen it will burn with more energy.
We are learning in BIO about the factors that denature the secondary and tertiary conformation of proteins and this guy Sevag tested how physical agitation can effect proteins. By merely putting chloroform and albumin in a test tube and shaking it.
The glowing splint will relight if you place it in a flask with oxygen. Scientists do this as a test for oxygen so if it relights, then that means the flask contains oxygen.
A glowing splint will burst into flame/smoke in pure oxygen (using a test tube).
