Question

Carbon plays an important role in our life. Explain ( 6 points )

Open in App
Solution

All life on our planet is "carbon-based". This is because Carbon is found in the really important components of life; proteins and nucleic acid. In fact, our life is called carbon-based, even though other elements, like oxygen, nitrogen, and hydrogen are also abundant, because carbon makes up the "backbone" of amino acids.

Most living things on Earth are made of carbon. Living things need carbon in order to live, grow, and reproduce. Carbon is a finite resource that cycles through the Earth in many forms. This makes carbon available to living organisms and remains in balance with other chemical reactions in the atmosphere and in bodies of water like ponds and oceans.

Uses of Carbon in Everyday Life

There are many limited uses of carbon in its elemental form. But once it combines with another element, it changes itself into a useful substance for numerous things.
  • Carbon is used as a base for the ink in inkjet printers.
  • Carbon, in the form of carbon dioxide, is used in the manufacture of many fizzy and carbonated drinks. It is also used in fire extinguishers.
  • Dry ice, which is the solid form of carbon dioxide, is used as a cooling agent.
  • Freon, is used in cooling systems and devices like refrigerators and air conditioners.
  • Carbon is also used to manufacture many heat resistant devices and tools and metal cutters.
  • It is used as a decorative tool in many jewelry items.
  • Carbon monoxide, extracted through metallurgical process, is used as a reducing agent to obtain many elements and compounds.
  • Vegetal carbon, which is an amorphous form of carbon, is utilized as a bleaching agent and a gas absorbent.
  • Carbon is used in the rim of automobiles as a black fume pigment.
  • Calcium carbide is used as a welding agent for cutting metals, in the preparation of acetylene and other organic compounds.


Some other uses of carbon depending on their form are:

Graphite: Graphite is one of the softest substances and is an allotrope of carbon. There are many industrial uses of graphite, like in the form of coke, which is used in the production of steel, as a lubricant for machinery and engines and as writing material, in the form of lead for pencils.

Diamond: Diamond, which is another allotrope of carbon, is the hardest known substance known to man. Diamonds are commercially used for making jewelry. Since these crystalline rocks are rare in nature, diamonds are very precious. Apart from jewelry, diamonds are also used for making cutting instruments because of their hardness.

Carbon Dating: This is a method used to determine the accurate age of fossils and minerals that have been found buried for many centuries in the Earth's crust. There are many isotopes of carbon that are used for this purpose, the main radioactive isotope being carbon -14. The main reason why carbon was chosen for this technique is the fact that life is based on the various compounds of carbon and it has a radioactive isotope, which makes it easy to determine the age of fossils.

Carbon in the Body: The human body contains large amounts of this element which is utilized for various functions. Carbon is a macronutrient and is present in every part of the body. Carbon dioxide in blood plays an important role in the body as it helps in maintaining the pH of blood.

Carbon is an essential element which has a lot of benefits for both industrial purposes and as the basic building block of the human body, without which, life is incomplete.
