What is Chemistry?

It is the branch of science which deals with the study of composition, properties and interaction of matter.

Definition of Chemistry

Chemistry is the scientific study of matter and substances for how they combine, separate, react or interact with each other.

Types of Chemistry

Chemistry is generally (as per basic chemistry) classified into three classes i.e. Physical chemistry, Organic chemistry and Inorganic chemistry. 

1. Physical Chemistry

Physical chemistry is the branch of chemistry. Physical Chemistry utilizes applications of physics to chemical systems to understand their physical properties.
Physical chemistry is the study of atomic, subatomic, macroscopic, microscopic or particulate phenomena in chemical systems in terms of different laws and concepts of physics. Physical chemistry applies the principles and concepts of physics such as thermodynamics, force, time, energy, motion, statistical mechanics, quantum chemistry, dynamics and equilibrium.
 
Physical properties of different type of chemical substances can be studied on different scales like atomic, subatomic, macroscopic and microscopic…….. read more

2. Organic Chemistry

Organic chemistry is a branch of chemistry which involve the scientific study of structure, properties & reactions of organic species, compounds or organic materials, means matter have various forms found that contains carbon atoms. Study of structure of organic chemistry compounds includes use of spectroscopy techniques like IR Spectroscopy, Microwave Spectroscopy, NMR Spectroscopy, Mass Spectroscopy, X – Ray Diffraction, Electron Diffraction, Neutron Diffraction and other physical and/or chemical type of methods to examine chemical composition and chemical constitution of the organic chemistry compounds and materials to be analysed. This is article on what is organic chemistry at “chemistry notes info blog”. Study of properties of organic compound includes study of both physical properties as well as chemical properties of organic chemistry compounds, which uses the similar methods and also methods to evaluate the chemical reactivity to understand behavior of organic matter (organic sample) in its pure form (if when possible), otherwise in solution, mixture forms. Study of chemistry of organic reactions includes the searching their possibility through use in the preparations of goal molecule or compounds like natural products, medicinal drugs, polymers, solvents, etc.) by their chemical synthesis, also focused on the study of  reactivity’s of the individual organic molecules…. read more 

3. Inorganic Chemistry

Inorganic chemistry is the branch of chemistry, which deals with the study of inorganic compounds and organo-metallic compounds. Inorganic chemistry includes study of all chemical compounds excluding organic compounds (where, organic compounds are carbon based compounds, generally having carbon-hydrogen bonds i.e. C-H bonds. 
 

Example of Inorganic Compound

Salt Magnesium Chloride (MgCl2) is an ionic Inorganic Compound which contains magnesium-cations Mg2+ and chloride-anions Cl
 

Branches of Inorganic Chemistry

Descriptive Inorganic Chemistry
Descriptive inorganic chemistry based on the arrangement and ordering of compounds based on their properties.

Coordination Chemistry

Coordination chemistry is the branch of Inorganic chemistry which deals with the study of coordination compounds or coordination complexes. A coordination compound or coordination complex contains of a central atom or ion, which is generally metallic and is known as coordination center, and get surrounded by group of bounding molecules or ions, these surrounding molecules and ions are known as ligands.

Materials Science

Material science deal with the study of materials. Study of metals, semiconductors, polymers, ceramics, nanomaterials, biomaterials and many other form of materials comes under material science. A material scientist……….. read more 

4. Analytical Chemistry

Analytical Chemistry is the branch of chemistry deals with the study of material examination to separate out them into different components and identifying all components and how much these components present in material. There are different analytical methods and techniques to perform these tasks.

What is Analytical Chemistry ?

Analytical chemistry is all about, what an analytical chemist do in an analytical chemistry lab. And simply we can say that analytical chemistry is the branch of chemistry for qualitative analysis and quantitative analysis of compounds and mixtures by using different test methods and techniques like flame tests, chemical tests, precipitation… read more

Branches of Chemistry ?

These are the some of general and important branches of chemistry-

Chemical Test

In Chemistry, Chemical Test are performed to measure or analyze Biochemical, Organic and Inorganic elements and chemical compounds. Chemical testing of water, chemical composition analysis of any compound, chemical test for organic compounds, chemical test for inorganic compounds, chemical test for functional groups, elemental analysis, chemical testing of food for its ingredients and to detect presence of any sort of insecticide pesticide in it, chemical test perform in chemistry labs etc are the some examples where we perform chemical tests. Now we think you have now somewhat idea to give answer of question what is chemical test?

chemical tests

What is Chemical Test

In the scientific field of chemistry, chemical tests are the methods to detect the presence and amount of chemical compound or chemical group with the help of some chemicals or reagent. Chemical tests are performed according to chemical testing methods in chemical testing labs for elemental analysis and chemical composition analysis.

Chemical Test Definition

Chemical test is a qualitative or quantitative method intended to confirm the presence and amount of a chemical compound or chemical group with the help of chemicals or specific reagent.

Chemical Testing Methods

Chemical testing methods are step by step procedure to perform some sort of chemical tests. These procedures are written and proven for its quality testing to deliver results with high accuracy. Generally chemical testing labs have SOPs (Standard Operating Procedures), these SOPs provide step by step guidance to a chemist to perform specific test.

Chemical Analysis Methods

Their are so many chemical analysis methods, below is the list of some of them-

Acid Test 

                Test which are performed with the help of acids like Acid Test of Gold.

Barfoed’s Test 

                      It is a chemical test performed to detect the presence of monosaccharides in the sample

Bromine Test 

                  In organic chemistry, It is a qualitative test to detect the presence of unsaturation ( means carbon-to-carbon double bonds or carbon-to-carbon triple bonds) and phenols.

Carbylamine Reaction

It is also known as Hoffman’s Isocyanide Test. This chemical test is performed to detect primary amines.

Flame Test

                In inorganic chemistry, Flame test is performed to detect metals, elements or chemical compounds as they produce some characteristic colors.
