Question

What is used to test for the presence of Oxygen?

Answer 1

• Oxygen$\left({\mathrm{O}}_2\right)$ is a colorless, odorless gas that is naturally found in nature.
• Combustion is the process of burning in the presence of oxygen
• A glowing splint test is used to detect the presence of oxygen.
• In the glowing splint test, the splint is ignited, and burn it for a few seconds, and blown out or shaken out of the mouth.
• Now, to check the presence of oxygen the splint is inserted into the gas-collected container.
• Coal is exposed to concentrated oxygen gas ignites to form a stable flame.
• Higher is the concentration of oxygen, the faster will be the wood burns and the stable will be the flame which indicates the presence of oxygen.
