Electrochemistry basically deals with conversation of  electrical energy to chemical energy & vice-versa. In These two types of cell ( battery) comes 1) electrolytic cell 2) galvanic cell. 1) electrolytic cell : In this electrical energy is converted into chemical energy. To produce chemical energy the electrical current is passed. e.g. for electroplating These cells are used. 2) galvanic cell : In this electrical energy is produced due to chemical energy. It is spontaneous process. In this no external electrical energy is supplied. e.g. lithium ion battery. In the construction of cel ..read more

Base - it is any compound which gives OH- ions in the solutions. Base can be further classified as 1) weak base 2) strong base 3) organic base 4) inorganic base. 1) weak base :- A base which does not dissociates completely in the solution is known as weak base. e.g. NH3 2) Strong base :- A base which dissociates completely in the solution is known as strong base. e.g. NaOH 3) organic base:- an organic compound which acts as a base is known as organic base. e.g. pyridine, methylamine. 4) inorganic base:- an inorganic compounds which has ability to neutralize the orgaic compound & produc ..read more

Acid : It is a substance (compound ) which Gives H+ ions in the solution. We can classify acid in following categories. 1) organic acids 2) inorganic acids. 3)strong acid 4) weak acid 1) organic acids : These are carbon containing acids . e.g carboxylic acid ( - COOH), citric acid (C6H8O7)  , latic acid (C3H6O6), Oxalic acid (C2H2O4). 2) Inorganic acid : The acids which does not contain carbon. e.g.  H2SO4( sulphuric acid) , NH3 ( Nitric acid ), HCl etc. 3) strong acid : The acid which completely dissociates in solution is called strong acid. e.g.HCL , H2SO4, HNO3. 4)weak acid : The acid ..read more

Chemical bond :- a bond between two atoms is formed when there is sharing of electrons or gain/loss  to form a stable compounds. Type of chemical bonds : 1) covalent bond : it is formed when there is sharing of electrons between two atoms. Also known as π-π bond . ( Lateral overlap) E.g -CH4 , CO. 2) coordinate- covalent bond : It is formed when there is sharing of lone pair of electrons between non-metal to metal. E.g-.  Comples 3) ionic bond : it is formed by gain or loss of electrons between two atoms . Also known as  sigam bond ( axial overlap). E.g -. NaCl. 4) Hydrogen bonds : it is ..read more

Definition: The branch of chemistry which deals with study of carbon & carbon related compounds is known as organic chemistry. When reactant gets converted into product between that the reactive intermediate are formed. 1) carbonations : The spaces carrying positive charge on carbon atom and having only 6 electrons in its outer valence shell are known as carbonations. 2) carbanions :- the species carrying negative charge on carbon atom and having 8 electrons in its outer valency are known as carbanions 3) free radicals :- an atom having odd number of electrons is known as free radical ..read more

What is nanotechnology? Nanotechnology deals with the material having size in the nanometres. If we consider  study of any metal at nano level we find change in the properties of that metal. e.g. colour ,electroconductivity  Case-1 :  If consider gold ( Au - aurum -79) it has yellowish colour by naked eyes. If  we divided the gold in number of parts then its solution will give different colours like blue, red, green , sky blue etc.  Case - 2 : If consider altropes of carbon diamond , graphite , fullerene .  A single layer of graphite will give us graphene which has totally different propert ..read more

Feline coronavirus (FCoV) is a positive-stranded RNA virus that is infectious to cats worldwide.  .Ribonucleic acid (RNA) is a polymeric molecule essential in various biological roles in coding, decoding, regulation and expression of genes. RNA and DNA are nucleic acids, and, along with lipids, proteins and carbohydrates, constitute the four major macromolecules essential for all known forms of life. This virus is part of the species Alphacoronavirus 1 of the genus Alphacoronavirus belonging to the virus family Coronaviridae. Nice Alphacoronavirus 1 also includes the canine coronavirus (CC ..read more
