Obtain Oxygen – Obtain Oxygen with Different Methods
Introduction – Obtain Oxygen
Obtain Oxygen is a tasteless, odourless and colourless gas. It is the next most abundant gas on earth after hydrogen. It is a potent oxidizing agent and also a chemically active nonmetal. This gas was discover simultaneously by several scientists in the 18th century, and the first scientist to obtain oxygen was the Swedish chemist Scheele in 1772. The French chemist Lavoisier studied the element and named it “Oxygen”. You can detect oxygen with a burning piece of wood, which catches fire in contact with the gas.
The Importance of Oxygen
This gas is involved in combustion processes, and also oxygen is processed by green plants, which use their leaves to carry out the procedure of photosynthesis, enriching the atmosphere with vital gas.
How can we get oxygen? The gas is extracted from the air using industrial processes that clean and compress the air. Our planet has vast reserves of water, the chemical composition of which is partly oxygen. It means that gas can be obtained by splitting water. Hence We can do it at home.
How do you Get Oxygen from Water?
The following tools and materials are required for the experiment.
- energy source
- two plastic cups
- 2 electrodes
- Galvanic bath
Let’s examine the process. In a galvanic bath, pour water up to half and add 2 ml of caustic nitrate or diluted sulfuric acid; this increases the electrical conductivity of the water. Therefore make holes in the bottom of the plastic cups and pull the electrodes through the holes – carbon plates. We need to insulate the air layer between the cup and the saucer. The cups are place in the bathtub so the electrodes are in the water and the cups upside down. There should be a minimum of air between the water’s surface and also the cup’s bottom.
We solder a metal wire to each electrode and also connect them to the power source. The electrode attached to the negative pole is called the cathode, and also the anode is connected to the positive rod.
A chemical reaction occurs, producing two gases. The hydrogen accumulates in the box with the cathode and also the oxygen in the box with the anode. The fact that gas has form in the cups with the electrodes can be seen by the air bubbles escaping from the water. We direct the oxygen from the cup to another container through a tube.
Safety Rules – Obtain Oxygen
The chemical attempt to extract oxygen from water should only be carry out in compliance with safety rules. The gases obtained during the electrolysis of water must be mix. The hydrogen obtained must not come into contact with the air because of its explosive nature. For safe and also exciting experiments with different gases, click here.
How to Get Oxygen by the Laboratory Method?
Method One: Pour calcium permanganate into a test tube and place the test tube on a burner. The manganese crystal is heat, and also oxygen is release. Next, we capture the gas with a gas bath. Result 10 g of calcium permanganate release of oxygen.
5 g of nitrate is poured into a test tube, and the test tube is close with a refractory stopper with a glass tube. We put the test tube on a base and also a sand bath under it to prevent overheating. We light the gas burner and direct the flame to the test tube. The substance melts, and oxygen is release. We collect the gas through the glass tube in a balloon placed on top.
Third Method – Obtain Oxygen
we pour potassium chlorate into a test tube and put it on a gas burner after closing it with a glass tube with a refractory cork. Potassium chlorate releases oxygen when heated. We collect the gas through the line in a balloon placed on it.

The most mutual commercial method for producing oxygen is separating air using either a cryogenic distillation procedure or a vacuum swing adsorption process. Nitrogen and argon are also form by separating them from the air.
