Applications of Chemistry

Chemistry is not just mixing two substances in a test tube and observing a change in colour or texture. Instead, if one looks carefully, chemistry can be seen all around us. From the exchange of gases in the human body, to the devastation of life through atomic bombs, everything has chemistry attached to it.

There are some fields which function primarily on chemical applications. A few examples of such fields are:-

1. Health and sanitation

Chemistry provided mankind with a large number of life-saving drugs. We could find a cure for dysentery and pneumonia due to the discovery of sulphur drugs and penicillin. Besides this, life-saving drugs like cisplatin and taxol are effective for cancer therapy and AZT is used for AIDS victim.

2. Supply of Food

The study of chemistry provided the world with chemical fertilizers such as urea, calcium superphosphate, sodium nitrate, and ammonium sulphate. These chemicals have helped greatly in increasing the yield of fruits, vegetables, and other crops. Thus, we can cater to the ever-growing demand for food. It has helped to protect the crops from insects and harmful bacteria by the use of certain effective insecticides, fungicides, and pesticides.

3. Increase in Comfort, Pleasure, and Luxuries

Because of the advancements in science and the discoveries of chemistry, we lead a more comfortable life today.

  • Synthetic fibres: These are more attractive, comfortable and durable. They include terylene, nylon, and rayon. They are easy to wash, dry quickly and do not need ironing. Chemistry provides a large number of synthetic dyes which imparts bright and fast colour to the clothes.
  • Articles of domestic use: Chemistry has made our homes more comfortable by supplying a large number of articles of domestic uses. Examples include detergents, oils, and fats, sugar, paper, glass, plastic, paints, cosmetics, perfumes, cooking gas etc.
  • Entertainment:Cinema, video cameras, simple cameras make use of films which are made of Celluloid and coated with suitable chemicals. Fireworks which amuse us on festival and marriages are chemical products.
  • Transport and communication: All means of transport use either petrol or diesel or coal which are all chemical products.
  • Nuclear atomic energy:Chemistry has come to the rescue by providing an alternative source of energy which is nuclear energy.

4. Chemistry in War

Chemistry plays an important role in the discovery of highly explosive substances such as TNT, nitroglycerine, and dynamite. It also plays a role in finding poisonous gases like mustard gas, Phosgene etc.

5. Nanochemistry

Nanochemistry unites – unsurprisingly – nanoscience and chemistry. Nanochemists work from the atom up, with the aim of engineering nanosized materials. They use a number of methods to prepare and assemble ‘little pieces of matter’ which display unique magnetic, electronic, optical, chemical and mechanical behaviors attributable only to their nanometer size. Nanochemistry has uses in chemical, physical and materials science, engineering and biological and medical applications.

Chemistry is a big part of our everyday life. We find chemistry in the food we eat, the air we breathe, the soaps we use, our emotions and literally every object we can see or touch. We live in a world of matter. The human body itself is a mixture of matter of different types.

Hence chemistry is very important efficient life style, in fact it is essential for our very survival.
