being lit, with the flame blown out, leaving an ember at the tip. Upon exposure to high concentrations of oxygen, the glowing ember flares and gives a flame.
Copper sulfate does not extinguish a lighted splint. When a lighted splint is exposed to copper sulfate, the flame may change color due to the presence of copper ions, but the splint will continue to burn as long as there is sufficient oxygen available for the combustion reaction to occur.
Yes, hydrogen gas will extinguish a lighted splint with a distinctive "pop" sound, as it reacts with oxygen in the air to form water. This reaction releases a significant amount of energy, which is why it is used in combustion engines.
The easiest method is to collect it in an upturned test tube, and place a lighted splint into it. If it goes out, pops, etc. it's not O2. If it burns much brighter, it is.
The splint test is to test for the presence of oxygen. You light a small piece of wood (the splint), then blow it out. The end of the wood will still glow. If you put the glowing splint into a test tube with oxygen, it will relight. It you put the glowing splint into a test tube with carbon dioxide, it will stop glowing. A better test for carbon dioxide is to bubble it through a solution of limewater.
Well, honey, let me break it down for you. Argon is a noble gas that is colorless, odorless, and tasteless. It does not react with other elements, so it won't put out a lighted splint. And as for limewater, argon won't have any effect on it because it's just gonna mind its own business and not react with it. So, in a nutshell, argon is just a chill gas that likes to keep to itself.

the lighted splint would stop burning as Helium does not burn.
When a lighted splint is put into a glass jar of helium, the splint will immediately extinguish because helium is an inert gas that does not support combustion. The lack of oxygen in the helium prevents the splint from continuing to burn.
hydrogen
When you put a lighted splint in nitrogen, it will continue to burn but more slowly than in oxygen due to the lack of oxygen in nitrogen. Nitrogen is an inert gas that does not support combustion, so the splint will eventually go out.
Yes, hydrogen gas will extinguish a lighted splint with a distinctive "pop" sound, as it reacts with oxygen in the air to form water. This reaction releases a significant amount of energy, which is why it is used in combustion engines.
Carbon dioxide gas extinguishes a lighted splint by cutting off the oxygen supply needed for combustion. When carbon dioxide is bubbled through lime water, it forms calcium carbonate, which causes the lime water to turn milky.
Insert a lighted splint into the reaction test tube. If it extinguishes with a "pop" sound, Hydrogen is present. The duller the pop the purer the hydrogen is.---------------------------------------------------------------------------------------------P.S. that's a burning splint.
If a lighted splint is put near of a mouth of a test tube containing hydrogen gas squeaky pop sound is heard.
