Branches of Chemistry

 Hello! 

Today's topic is "Branches of Chemistry"

We are living in the world of chemicals. We all depend upon different living organisms which requires water,  oxygen or carbon dioxide for their survival. Chemistry had a wide scope in all aspects of life and is serving the humanity day and night. 

The five main branches of chemistry are organic, inorganic, analytical, physical, and biochemistry.

Now we will discuss about each branch. 

Organic Chemistry:

It is the study of  compounds of carbon and hydrogen and their derivatives. Organic compounds occur naturally and are also synthesized in the laboratory. It has applications in petroleum, petrochemicals and pharmaceutical industries. 


Inorganic Chemistry:

It deals with the study of all the elements and their compounds except those of compounds of carbon and hydrogen and their derivatives. It has applications in every aspect of chemical industry such an glass, cement, ceramic and metallurgy. 

Analytical Chemistry:

It is the branch of chemistry that deals with separation and analysis of a sample to identify it's compounds. It may be a qualitative analysis or quantitative analysis

Physical Chemistry:

It is the branch that deals with the relationship between composition and physical properties of matter. It also deals with the changes of matter. For example;behavior of solids, liquids and gases, structure of atom, effect of temperature or radiation on matter etc. 

Biochemistry:

It is the branch of chemistry in which we study about structure, composition and chemical reactions of substances found in living organisms. Biochemistry is the study of chemical reactions that occur in living organisms.The field focuses on nucleic acids, lipids, carbohydrates, and proteins.

These are main field of chemistry which I discussed today. In my next blog we will discuss more branches of chemistry.

Carbon Cycle

CARBON CYCLE: Carbon circulates through the carbon cycle. It shows that carbon may be pres- ent as gaseous atmospheric CO2 constituting a relatively small but highly significant portion of global carbon. Some of the carbon is dissolved in surface water and groundwater as HCO-3 or molecular CO2 (aq). A very large amount of carbon is present in minerals, particularly magnesium and calcium carbonates such as CaCO3. Photosynthesis fixes inorganic C as biological carbon. represented as (CH2O), which is a constituent of all life molecules. Another fraction of carbon is fixed as petroleum and natural gas, with a much larger amount as hydrocarbonaceous kerogen (the organic matter in oil shale), coal, and lignite. Manufacturing processes are used to convert hydro- carbons to xenobiotic compounds with functional groups containing halogens, oxygen, nitrogen, phosphorus, or sulfur. Although a very small amount of total environmental carbon, these com- pounds are particularly significant because of...

Chemical species

  Hello! Welcome to my blog. Today we will discuss about chemical species. lets start. If one  molecule  is identical to another, we can say they are the same chemical species. Ion: It is an atom or group of atoms having a charge on it. The charge may be positive or negative.  There are two types of ions:       Cations: An atom or group of atoms having positive charge on it is called cation. They are formed when atoms lose electron from their valance shells. Examples:   Ca 2+   Ag +    Al 3+     H 3 O +     NH 4 +     Hg 2 +2      Fe +2     Fe  +3        Anions: An atom or group of atoms having negative charge on it is called anion. They are formed by gain or addition of electron to an atom. Examples: Cl –    OH –      I –     Cr 2 O 7 -2     O -2      SO ...

Cycles of Matter

 Very much connected with environmental chemistry, cycles of matter, often based on elemental cycles, are of utmost importance in the environment. Global geochemical cycles can be regarded from the viewpoint of various reservoirs, such as oceans, sediments, and the atmosphere, connected by conduits through which matter moves continuously among the hydrosphere, atmosphere, geo- sphere, biosphere, and, increasingly, the anthrosphere. The movement of a specific kind of matter between two particular reservoirs may be reversible or irreversible. The fluxes of movement for particular kinds of matter vary greatly as do the contents of such matter in a specified reservoir. Most cycles of matter have a strong biotic component, especially through the biochemical processesof plants and microorganisms. The cycles in which organisms participate are called biogeochemical cycles, which describe the circulation of matter, particularly plant and animal nutrients, through ecosystems. Most biogeoche...
