Testing for oxygen in a laboratory is essential for various experiments and processes. Here’s a simple guide to help you perform this task using basic techniques.

Materials Needed

  • Glowing splint
  • Test tube
  • Manganese dioxide (MnO2)
  • Hydrogen peroxide (H2O2)

Procedure

  1. Add a small amount of manganese dioxide to a test tube.
  2. Carefully pour hydrogen peroxide into the test tube.
  3. Observe the reaction and the production of gas.
  4. Introduce a glowing splint into the mouth of the test tube.

Observation

  • If the glowing splint reignites, it confirms the presence of oxygen.

By following these steps, you can easily test for oxygen using simple laboratory techniques.
