Science in its totality is the study of the objects, surroundings and various natural events and their effects based on experiments and observations. It encompasses a systematic and logical approach towards the behavior of changes around us and the events concerned with them. The curiosity of the human brain for understanding the world and things that are beyond this world has led to the development of various laws and principles.
Science has helped the human brain to understand its surrounding very precisely which in turn has resulted in numerous discoveries and inventions. These discoveries and inventions have improved the standard of living on this planet and have paved the way for further studies.
Science has been divided into different sub-groups based on their concerned area of study. Chemistry is a branch of science that deals with matter, particularly the study of atoms and molecules and the parameters that govern their inter-convertibility.
What is Chemistry?
Chemistry is one of the basic branches of science that deals with the properties, structure, and constituents of matter or substances and its interactions with other forms of matter. There is a lot of difference that can be seen when you compare Basic Chemistry and Modern chemistry.
Basic Chemistry originated in ancient times at the hands of famous scientists called Alchemists. It explained all the basics of the subject which were concluded after a series of experiments which shed light on how they really worked. Whereas Modern Chemistry prevailed in the 17th century which laid systematic steps in gaining knowledge about the matter. Modern chemistry brought about various theories which finally became justified with the experiments they conducted to prove how matter interacts.
The domain of chemistry comprises of the study of the composition of matter, its structure, and properties. The fundamental constituents of matter, atoms & molecules, form the basis of chemistry. Chemistry has provided answers to various questions. The quantitative measurement of the number of basic constituents of matter i.e. atoms and molecules and their dependence on the mass of the given matter is well explained by chemistry. Advances in chemistry have helped scientists and engineers to harness the energy associated with these atoms & molecules.
Today we can preserve food items for long duration’s of time; we have millions of chemicals that are being used in different industries for manufacturing a variety of products. Cell phone covers, plastic bags, the steel used in construction, the pasteurized milk, photosynthesis, the crackers we burn, etc. are only a few examples of products of chemistry. These products are such deeply rooted in our lives that we fail to visualize their importance and the role of the science behind them.

Main Branches of Chemistry
Due to the vast variety of interactions possible between matter in general, there are said to be five branches of Chemistry namely organic chemistry, analytical chemistry, inorganic chemistry, biochemistry and physical chemistry. The details about them are explained below-
It is a branch of chemistry which deals with the study of carbon-based compounds. It mainly applies to the study of the behavior, characteristics, compositions and the properties of the organic compounds. It is also known as The Chemistry of Life.
A branch of chemistry that deals with the study of metals and gaseous matter or materials which do not contain carbon as an element in it is called Inorganic chemistry. It is opposite side of Organic Chemistry.
The combined study of using physics and chemistry to explain chemical systems is called Physical chemistry. This branch relates to the physical properties along with the structure of matter and energy. The sub-branches coming under this field are quantum physics and thermodynamics.
Biochemistry is a branch of chemistry which deals with the study of the chemical processes that takes place in living organisms. Hence the name Biochemistry.
It is an interesting field of chemistry that studies the properties of matter, along with the composition of different substances and materials. This branch of chemistry uses quantitative methods for the identification of chemical and physical properties of matter.
As you might be aware of common salt which we use in our foods, Have you ever observed what happens when the elements of these substances are involved in reactions?
Consider the sodium metal element when it reacts with water it produces a kind of hissing sound by giving out hydrogen as a gas. This is due to the chemical reaction which makes it happen. The equation for this chemical reaction can be represented as given below :
Na + H2O → NaOH + H2
On more reaction would be the chemical reaction between sodium and chlorine. There is a formation of Sodium chloride or commonly known as common salt. Likewise, there are many chemical reactions taking place within and around us all which are all by the phenomenon of chemistry.
Types of Chemical Reactions
These are the more common types of chemical reaction:-

Frequently Asked Questions on Chemistry
What is a chemical change? Is cooking an egg a chemical change?
There are changes all around us like sugar dissolves in water, the lake freezes in winter etc. Some changes are what scientist call chemical changes and some are not. A chemical change takes place when a new substances are made that are different from the substances that we started with.
Yes Cooking eggs, for instance, is an example of a chemical change; the egg white and egg yolk change from liquid to solid. The heat makes the proteins in the egg hardens.
Which acid is called “Kingly Water” and why?
Aqua Regia is the Kings Water, this is because it is strong enough to dissolve gold – the king of metals. It is prepared by mixing three parts of hydrochloric acid with one part nitric acid but in olden days it is prepared mixing and distilling salts. For example, we can mix two parts niter with one part Sal. Ammoniac and distill at a high temperature to form Aqua Regia.
“Sulphuric acid” is called the king of acids and “Nitric acid” is called the Queen of acids.
What are the main branches of chemistry?
Chemistry is the science that studies atoms and molecules along with their properties. All matter is composed of atoms and molecules. There are 5 main branches of chemistry are
- Organic chemistry
- Inorganic chemistry
- Physical chemistry
- Analytical chemistry
What is the importance of organic chemistry?
Organic chemistry is simply the study of carbon compounds. Organic chemistry is important because it is life studies and all life-related chemical reactions.Organic chemistry initially involves the study of compounds that could be obtained from living organisms.
Approximately 7 million different organic compounds are known present while there are only 1.5 million known inorganic compounds.This large number of organic compounds arise from the unique property of carbon.
Which compound is known as “Blue Vitriol”?
Blue vitriol is also known as blue copperas. The word blue vitriol has a strict and definite meaning. It means sulphate of copper with the chemical formula CuSO4.5H2O. The chemical name for blue vitriol is Copper (II) Sulphate Pentahydrate. This salt occurs in the form of rhomboidal prisms of a deep blue colour, having an exceedingly harsh and styptic taste.
