What Is Õygen? – For Newbies!
Õygen, commonly known as oxygen, is the life-sustaining gas that fuels the fire of existence. It is the breath of life, the invisible force that keeps our bodies thriving.
Essential for the survival of most living organisms, Õygen plays a pivotal role in various biological processes, ensuring the vitality of life on Earth.
The Origins And Meaning Behind The Name – Exploring The Fascinating Tale!
Oxygen was identified around 1772 by a Swedish chemist named Carl Wilhelm Scheele. He obtained it through the heating of various substances, including potassium nitrate and mercuric oxide.
Independently, English chemist Joseph Priestley also discovered oxygen in 1774 by thermally decomposing mercuric oxide and published his findings that same year—three years before Scheele’s publication.
Between 1775 and 1780, French chemist Antoine-Laurent Lavoisier provided significant insights into the role of oxygen in respiration and combustion.
Lavoisier rejected the previously accepted phlogiston theory and observed oxygen’s capacity to form acids when combined with various substances. Consequently, he named the element oxygen (oxygène), drawing from the Greek words signifying “acid former.”

Õygen isn’t just a passive player; it’s a dynamic force with incredible capabilities. It supports combustion, enabling fire to flicker and warm our nights. Its role in respiration is unparalleled, sustaining the energy needs of complex organisms.
As a crucial component of air, Õygen also influences climate and weather patterns, showcasing its far-reaching impact on the planet.
The choice of production methods for oxygen is contingent upon the desired quantity of the element. Laboratory techniques encompass the following.
Preparative Methods Of Õygen – Check This!
1. Thermal decomposition of salts like potassium chlorate or potassium nitrate:
Catalyzed by transition metal oxides, particularly manganese dioxide (pyrolusite, MnO2), the decomposition of potassium chlorate is a common method. The catalyst reduces the required temperature for oxygen evolution from 400 °C to 250 °C.
2. Thermal decomposition of oxides of heavy metals:
Mercury(II) oxide, employed by Scheele and Priestley in their oxygen preparations, is an example of an oxide of a heavy metal undergoing thermal decomposition.
3. Thermal decomposition of metal peroxides or hydrogen peroxide:
Early commercial processes for oxygen isolation from the atmosphere or hydrogen peroxide production relied on the formation of barium peroxide from the oxide, as indicated in the equations.
4. Electrolysis of water with added salts or acids for conductivity:
This method involves the electrolysis of water with added salts or acids to enable the conduction of electric current, as represented in the chemical equation.
Commercial Production And Use Of Õygen – Explore The Possibilities!
When oxygen is needed in large quantities, it is produced through the fractional distillation of liquid air. Among the main components of air, oxygen has the highest boiling point, making it less volatile than nitrogen and argon.
The process exploits the cooling effect that occurs when a compressed gas expands. The key steps in this operation include:
1. Filtering Air: Removing particulates from the air.
2. Moisture and Carbon Dioxide Removal: Absorbing moisture and carbon dioxide using alkali.
3. Air Compression: Compressing air and removing the heat of compression through standard cooling methods.
4. Cooling in Coils: Passing the compressed and cooled air into coils within a chamber.
5. Expansion in Chamber: Allowing a portion of the compressed air (at around 200 atmospheric pressure) to expand in the chamber, cooling the coils.
6. Multiple Compression and Expansion Steps: Returning the expanded gas to the compressor with multiple expansion and compression steps, eventually liquefying the compressed air at a temperature of −196 °C.
7. Distillation of Liquid Air: Allowing the liquid air to warm, distilling light rare gases first, followed by nitrogen, leaving liquid oxygen.
Repeated fractionation produces a product pure enough (99.5 percent) for most industrial purposes.
1. Oxygen Applications in Various Industries:
In industry, pure oxygen is vital for the steelmaking process, enhancing the purification of high-carbon steel by swiftly eliminating carbon dioxide and other impurities.
It is also promising for sewage treatment, providing a more efficient solution compared to traditional chemical methods. Closed-system incineration using pure oxygen has gained importance in waste disposal.
Liquid oxygen (LOX) serves as rocket fuel, its usage dictated by space program activities. In other sectors, commercial oxygen or oxygen-enriched air has replaced regular air in the chemical industry, facilitating the production of controlled-oxidation chemicals.
Medical applications include oxygen tents, inhalators, and pediatric incubators, while oxygen-enriched gaseous anesthetics ensure life support during general anesthesia. Oxygen remains critical in various industries utilizing kilns.
