Oxygen gas can be produced from water through a process called electrolysis. In electrolysis, water is split into its components, hydrogen and oxygen, using an electric current. The oxygen gas is collected at the anode while hydrogen gas is collected at the cathode.
Oxygen gas is primarily produced through the process of photosynthesis in plants and algae, where carbon dioxide and water are converted into glucose and oxygen using light energy. Oxygen gas is also produced through chemical reactions like electrolysis of water and decomposition of hydrogen peroxide.
Photosynthesis
Water can be electrolyzed by passing an electric current through it, which causes the water molecules to break apart into hydrogen and oxygen gases. This process occurs at the electrodes, where hydrogen gas is produced at the cathode and oxygen gas is produced at the anode.
Oxygen gas is produced when hydrogen peroxide is mixed with potassium iodide. This reaction results in the decomposition of hydrogen peroxide to water and oxygen gas as well as the formation of iodine.
Oxygen gas can be produced in the lab by heating a compound that contains oxygen, such as potassium chlorate, and collecting the gas released through a tube. Another method is through the electrolysis of water, where water is split into hydrogen and oxygen gases using an electric current.
Hydrogen and oxygen
If one chemically reacts oxygen gas and hydrogen gas, any liquid produced is water.
Water can not be produced by mixing these to gases, when hydrogen gas is burn in oxygen atmosphere the vapours of water are produced.
When electric current is passed through water, hydrogen gas is produced at the cathode. This is because water molecules (H2O) are split into hydrogen (H2) and oxygen (O2) gases through electrolysis. The hydrogen gas is evolved at the negative electrode, which is the cathode.
oxygen
The water displacement method is used in collecting oxygen because oxygen gas is less dense than water. As the oxygen is produced in a reaction, it displaces the water in the collection vessel, allowing the gas to be collected and measured. This method helps to accurately determine the volume of oxygen being produced.
In an electrolysis of water, hydrogen gas is produced in greater quantity compared to oxygen gas. This is because water molecules (H2O) consist of two hydrogen atoms and one oxygen atom, so the ratio of hydrogen to oxygen produced is 2:1.

When hydrogen peroxide reacts with catalase, an enzyme found in cells, it breaks down the hydrogen peroxide into water and oxygen gas. The oxygen gas is produced in the form of bubbles due to the rapid release of oxygen gas during the decomposition reaction. This reaction is catalyzed by catalase, which helps speed up the decomposition of hydrogen peroxide into water and oxygen.
