Chemistry is one of the basic sciences. Knowledge of
chemistry is indispensable for the pursuit of any of the other sciences. We
need it for the study of Technology, Pharmacology, Mineralogy, and what not. It
is indispensable for the study of physics, geology, biology and physiology.
Hence it is a compulsory subject of study for every science student.
In the modern industrial age this importance is even more
widely felt. It is needed in workshops, in laboratories, in medical clinics, on
farm lands, as well as in various manufacturing processes.
It would be almost impossible to enumerate all the
departments of science in which the services of the chemist are required or of
uses to which this science is put. Everything is made of chemicals. Many of the
changes we observe in the world around we see that caused by chemical
reactions. Chemistry is very important because it helps us to know the
composition, structure& changes of matter.
The Importance of
Chemistry
We are living in an age of synthetic products. The increased
demand for various natural products and the fact that they may not be easily
available everywhere has led to a new development in the world of chemistry.
Today natural products are often created artificially by chemical processes
Natural indigo has been completely superseded by equivalent synthetic dyes.
Real silk manufactured from the cocoon is a costly product and is not readily
obtained in all climatic conditions. This has given rise to a large industry of
artificial silk. There is nothing that cannot be done with plastics—from
clothing to buildings. These examples will give an idea of the role that
chemistry will play in the new age that is coming.
Ally of Medical:
In the science of medicine, the use of chemistry is fundamental. The men who dispense
the prescriptions of the physician are rightly called ‘chemists’. Chemical
research goes hand in hand with medical research. Thus the development of
organic chemistry has revolutionized the basis of modern medicine. The
discovery, of wonder-drugs like penicillin and streptomycin, and the
application of the chemistry of dyes to therapeutics have brought about
incalculable benefits to humanity.
How it helps
Dietetics: The new science of vitamins has added to the importance of the
chemistry of food. The war time shortage of food led to the invention of
various concentrated chemical foods and helped to make up deficiencies in the
quality and content of food. The science of Biochemistry indeed has developed
into an important branch of Chemistry, the value of which in relation to the
phenomenon of life is full of possibilities.
As an aid to
agriculture: The use of chemistry for the agriculturist is also very great.
Chemical fertilizers are effectively re-enforcing primitive forms of manure
greatly to the enrichment of the soil. Indeed, soil chemistry is a fruitful
subject of study and research, particularly in an agricultural country like
India.
In Wars – The
contribution of chemical science to military science involving destruction is
as great as its creative side. It has helped the large- scale production of
glycerin and nitric acid and thus stimulated the manufacture of high-grade
explosives in ever-increasing quantities.
Chemistry of today is actually helping in solving major
problems of our present day civilization such as population explosion ,food and
diseases, depletion of sources of energy and environmental problems. Green
chemistry lays emphasizes on processes and products that reduce or eliminate
the use and generation of hazardous substances.
