Simple method Preparation of Oxygen

What is oxygen?

oxygen is a colorless, odorless reactive gas, the chemical element of atomic number 8 and the life-supporting component of the air. Oxygen forms about 20 percent of the earth's atmosphere, and is the most abundant element in the earth's crust, mainly in the form of oxides, silicates, and carbonates.

How to Make oxygen with Simple method

Materials

dry battery 1.5V, dry battery 9V, hydrogen peroxide,water tank, 2 PET bottle , straw, steel wool, spirit lamp,match, deflagrating spoon, radio pincers, nippers, and glass bottle

Procedure

1. The hole for the straw to the cap of the PET bottle is made. Surroundings of the hole are closed with clay so that the gas should not leak here through the straw.
2. The water substitution is prepared by putting water in the water tank, and using the PET bottle.
3. The manganese dioxide and the hydrogen peroxide are put in the PET bottle, and the cap with the straw is done. The produced oxygen should be collected in the PET bottle quickly.Because the reaction will end in a short time, it is points.

Working

1. Oxygen is quietly put in the bottle.
2. The steel wool that sets fire by the spirit lamp is sent in. It is possible that steel wool can ignite with a dry battery of 9V. It is difficult to pour the oxygen into the bottle when ceiling fan is working. You can put the ignited steel wool directly in the PET bottle which has full of oxygen. However, it is noted to change the PET bottle’s shape easily because of heat. The spit can be used when there is no deflagrating spoon.
