Everything about chemistry

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 cells two rods are used 1) Anode - always oxidation occurs 2) cathode - always reduction occurs. Anode is positive in electrolytic cell Anode is negative in galvanic cell. Cathode is negative in electrolytic cell Cathode is positive in galvanic cell.

Functional groups interconversion.

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 & produce salt. e.g. calcium carbonate.
