Hydrogen oxygen generator oxygen properties and oxygen production method

First, the nature and use of oxygen

Physical properties of oxygen:

(1) Slightly denser than air.

(2) Under normal conditions, it is a colorless and odorless gas, which can be liquefied and solidified.

(3) not easily soluble in water.

Hydrogen oxygen generator oxygen properties and oxygen production method

Oxygen chemical properties: oxygen is a kind of chemical properties more active gas, can have chemical reaction with many substances, in the reaction to provide oxygen, oxidation, is commonly used oxidant. Comparison of combustion phenomena of substances in air and oxygen:

Uses of oxygen:

(1) Supply of breathing: for patients, mountaineering, diving, aviation and astronauts to provide oxygen for breathing.

(2) industrial used for iron and steel smelting and metal welding.

(3) Support combustion: the use of combustible reaction with oxygen release heat.

Two, the laboratory method of oxygen:

drug

(1) Potassium chlorate (KClO) and Manganese dioxide (MnO₂)

(2) Potassium permanganate (KMnO₄)

(3) Hydrogen peroxide solution (H2O), manganese dioxide (MnO₂)

Hydrogen oxygen generator oxygen properties and oxygen production method: reaction principle

The experimental steps

(1) potassium chlorate or potassium permanganate to produce oxygen

① Assemble the instrument and check the air tightness of the device

(2) with drugs

Fix the test tube on the iron rack

(4) Light the alcohol lamp to heat it

⑤ Use drainage to collect oxygen

⑥ Lift the catheter out of the water

⑦ Turn off the alcohol lamp

Hydrogen peroxide makes oxygen

1. Pack drugs

2, use drainage method to collect oxygen

3. Assemble the instrument and check the air tightness of the device
