Chemistry Definitions:�Chemistry is the outlet of Science concerned with Matter. It deals with the study of Composition of the Substances from Matter and also investigates properties and Reactions of Matter.�Branches of Chemistry is described below:

What is Chemistry?

Simple Definition of Chemistry

Science is basically the acquaintance which delivers a complete understanding of the facts of this world and how they work.

Chemistry is the branch of Science which deals with the Matter. It also explains the Composition, Properties,�and Reactions of matter with other Substances. InShort, Chemistry deals with every single facet of our life.

  • It is a statistic fact now a day man lived in the World of Chemicals.
  • In every aspect, all Human Beings are off and on dependent on the other different living organisms.
  • Which need Water. Oxygen or Carbon Dioxide for their life survival.
  • Nowadays Chemistry has a wide scope in all facets of life. It plays a vital role in serving the civilization day and night.
Branches of Chemistry

Branches of Chemistry

There are various�Branches of Chemistry. Chemistry is divided into main branches:

  1. Physical Chemistry
  2. General Chemistry�
  3. Organic Chemistry
  4. Inorganic Chemistry
  5. Biochemistry
  6. Industrial Chemistry
  7. Nuclear Chemistry
  8. Environmental Chemistry
  9. Analytical Chemistry

Branches of Chemistry Detail:

Physical Chemistry Definition

Physical Chemistry is well-defined as the branch of chemistry which deals with the association between the Composition as well as Physical properties of matter. In Physical Chemistry also study the Structure of Atoms, Formation of Molecules, Properties of Matter, Comportment of Gases, Liquids and Solids.�Physical Chemistry also deals with the Effect of Temperature or Radioactivity on Matter.

General Chemistry Definition

General chemistry is the branch of Chemistry which deals with the study of Matter, Energy, and the Interactions between Matter.

Organic Chemistry Definition

Organic Chemistry is the branch of Chemistry which deals with the Hydrocarbons. �It is the study of Carbon and Hydrogen Covalent Compounds and their derivatives. Organic compounds ensue naturally as well as manufactured in the laboratories. In the Organic Chemistry, chemists study the Structure and Properties of Organic Compounds. Organic Chemistry also deals with the Petroleum Industry, Petrochemicals Industry, and Pharmaceutical Industry.

Inorganic Chemistry Definition

Inorganic Chemistry is the branch of Chemistry which deals all Elements and Compounds excluding Hydrocarbons and their byproducts. Inorganic Chemistry is basically the study of all characteristic of the Chemical Industry.

Biochemistry Definition

It is the branch of Chemistry which deals with the study of Structure, Composition, and Chemical Reactions of various substances of the living organisms. Biochemistry is the study of all Chemical Processes occurring in the living organisms. Biochemistry developed as a discrete discipline when scientists instigated that How Living Organismsenergy from food or how the essential biotic fluctuations occur during a disease inside the body of Living Organisms. Biochemistry study widely provides knowledge about Medicine, Food Science and Agriculture Industry, etc.

Industrial Chemistry Definition

Industrial Chemistry is the branch of chemistry which deals with the manufacturing of Chemical Substance or compounds on the Commercial scale. Industrial Chemistry mainly deals with the production of rudimentary chemicals such as Oxygen, Chlorine, Ammonia, Caustic Soda, Nitric Acid, and Sulphuric acid. These compounds deliver the raw materials for many other industries such as FertilizersIndustry, Soap Industry, Textile Industry, Agricultural Products, Paint Industry, and Paper Industry, etc.

Nuclear Chemistry Definition

Nuclear Chemistry is the branch off Chemistry which chiefly deals with the Radioactive Compounds. It mainly deals with the Radioactivity, and Nuclear Processes. In this branch, Physical and Chemical properties of the Radioactive Compounds are also studied. The foremost apprehension of this branch is with Atomic Energy and its practices in daily life. It also comprises the study of the Biological effects of Atomic Energy resulting from the Absorption of Radiation inside Animals, Plants, and other materials. Nuclear Chemistry plays a vital role in Medical Treatment like Radiotherapy, Preservation of Food and Generation of Electrical Met with the help of Nuclear Reactors.

Environmental Chemistry Definition

Environmental Chemistry is the branch of Chemistry which deals with Environmental Biotic and Abiotic Factors. It also deals with components of the Environment and the mirrors of Human Activities on the Environment.

Chemistry Topics

The chief Topics in Chemistry (Branches of Chemistry) are:

  1. Acids and Bases
  2. Atomic Structure
  3. The Periodic Table
  4. Chemical Bonding
  5. Chemical Reactions
  6. Units and Measurement
  7. Electrochemistry
  8. Thermochemistry
  9. Equations and Stoichiometry
  10. Solutions and Mixtures

Acids, Bases, and pH

Acids, bases, and pH are notions that only smear on Aqueous Solutions. Aqueous Solutions are the solutions in water. pH is defined as Relative Concentration of Hydrogen Ion. It is also the capability of a species to donate/accept Protons or Electrons. Acid-base rejoinders are tremendously significant in all living cells and Industrial Processes.

Atomic Structure

Atoms are comprised of Protons, Neutrons, and Electrons. Protons and Neutrons present inside the Nucleus of Atom. While Electrons moved around the Nucleus in the specific path called Orbit. The training of Atomic Structure involves considerate the composition of Atoms, Isotopes, and Ions.


Electro Chemistry is principally concerned with Oxidation-Reduction Reactions. These rejoinders yield Ions. Electrochemistry is a second-hand study to forecast whether Redox Reaction will occur or not.

Units and Measurement

Chemistry is a science that depends on Experimentation processes. Which includes taking Measurements and Execution of Calculations on measurements basis. Due to this, it is very significant to be conversant with the units of measurement.


Thermo-chemistry is the area of general chemistry that relates to thermodynamics. Thermochemistry involves the concepts of entropy, enthalpy, Gibbs free energy, standard state conditions, and energy diagrams.

Chemical Bonding

Atoms and Molecules join together by Ionic and Covalent Bonding. This knowledge includes related to Electronegativity, Oxidation Numbers, and Lewis Electron Dot Structure.

Periodic Table

The Periodic table is in short, a methodical way of establishing the Chemical Elements. Elements parade various Periodic Properties which show differentCharacteristics.

Equations and Stoichiometry

This study is useful to acquire how to Balance Chemical Equations. And what are Different Factors which distress the yield of Chemical reactions?

Solutions and Mixtures

It is knowledge about different Solutions and Mixtures types. It is also the study of how to Calculate Concentrations of Chemical Reactions. This grouping contains topics such as Colloids, Suspensions, and Dilutions.
