Question

Give a test by which we can identify oxygen......zaldi do answer pls​

Answer 1

For the identification of oxygen :-

• By burning a matchstick near the oxygen supply it would burn more brightly.

Answer 2

Explanation:

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. There are sometimes confusions as the splint can create a pop very slightly on re-ignition, which sometimes is mistaken for hydrogen. A hydrogen pop is much more violent, sometimes enough to completely extinguish the splint.
