The first element in the periodic table to have an atomic number one is hydrogen. Hydrogen consists of only one electron and one proton. During the combustion of hydrogen and oxygen, water is produced as a by-product. Water is the most common form. Hydrogen on the Earth’s surface may be found in various other compounds, including oxygen, carbon, and nitrogen. Hydrogen has chemical similarities with both alkali metals and halogens. Because of its distinctive features, it has been assigned a specific place in the periodic table. Let us learn about its properties and uses of hydrogen or liquid hydrogen uses in detail.
Occurrence of Hydrogen
According to some estimates, hydrogen is the most prevalent element in the cosmos and on Earth. It is estimated that hydrogen atoms account for almost nine out of every ten atoms in the universe. It is possible to find hydrogen in its free form in certain volcanic gases, and it can also be found at high concentrations in the outer atmospheres of the sun and other stars across the galaxy. Let’s know more about the properties and uses of hydrogen.
Physical Properties of hydrogen
Learn about the major physical properties of hydrogen:
Unlike other gases, hydrogen does not have an odour or taste.
Hydrogen acts as a reducing as well as an excellent oxidizing agent.
It is the smallest known chemical element with an atomic mass of 1.0079 amu.
Hydrogen is a highly flammable diatomic gas.
It is the only gas having the lowest density.
Hydrogen is non-toxic and may be safely produced, transported, and stored in huge quantities from various sources.
As a gas, it is present in one-millionth of the volume of the air we breathe.
It acts as a storage device for energy that has been generated elsewhere.
The liquefaction temperature for hydrogen is -252 °C.
Hydrogen has a boiling point of -259.14 in its gaseous state°C, which becomes liquid hydrogen.
Chemical Properties of Hydrogen
Learn about the major chemical properties of hydrogen:
An enormous amount of energy is released in water from hydrogen and oxygen. Electricity is generated in fuel cells using this.
2 H2 + O2 → 2 H2O
Hydrogen combines with oxidizing elements to generate hydrogen halides, reacting strongly and spontaneously with chlorine and fluorine.
H2 + X2 → 2 HX (X = F, Cl, Br & I)
Despite its high stability, H2 can combine with most other elements to generate new compounds.
Hydrogen may have a partial positive charge when interacting with more electronegative elements like halogens or oxygen. In contrast, hydrogen can have a partial negative charge when reacting with more electropositive elements like alkali metals.
As a reducing agent, hydrogen works on its own. Whenever unsaturated organic molecules are combined with finely split nickel, the result is the formation of saturated organic compounds.
Uses of hydrogen
Learn about the various uses of hydrogen. Hydrogen has a wide variety of uses. Some of them are:
Hydrogen is employed as rocket fuel in a variety of space research endeavors.
The use of hydrogen gas in air balloons for the flight was made possible because it is lightweight and inexpensive.
It is utilized to produce valuable molecules such as ammonia, water gas, methyl alcohol, and other similar substances.
In metallurgy, it is an excellent reducing agent that has several applications.
The usage of hydrogen as a power source is common.
It is utilized in the hydrogenation of oils, which is necessary for the production of vanaspati ghee.
The production of ammonia is the most prominent use of hydrogen.
Heavy water is created by using an isotope of hydrogen (D2O). Nuclear reactors employ heavy water as a coolant.
Everyday use for hydrogen gas is sulphur removal in the petroleum sector.
A zero-emission fuel, hydrogen fuel is created when hydrogen reacts with oxygen to produce heat and combustion.
Conclusion
In addition to its role in the process of enzyme catalysis, hydrogen is necessary for the stabilization of nucleic acids and proteins. Compounds are formed when hydrogen forms bonds with a variety of different elements. Hydrogen is significant because it provides the Earth with a new fuel source and can eliminate the need for fossil fuels in the future. The usage of hydrogen has a significant impact on reducing pollution. When hydrogen and oxygen are mixed in a fuel cell, electricity is generated due to the reaction. Development, transportation, and product manufacturing expenses will become more inexpensive as hydrogen use grows and technological advancements take hold, making them more economical. Here we learn about hydrogen’s various properties and uses and liquid hydrogen uses.
