Oxidation Number or Oxidation State

Science > Chemistry > Redox Reactions > Oxidation Number or Oxidation State Oxidation Number OR Oxidation State: The donation of electrons is called the oxidation and the gain of electrons is called the reduction. Oxidation and reduction can further be explained by a knowledge of “Oxidation number”. The oxidation state of an atom in its […]

Introduction to Redox Reactions

Science > Chemistry > Redox Reactions > Introduction to Redox Reactions In this article we shall study about redox reactions, in which both the oxidation and reduction reactions take place simultaneously. Oxidation: Old Concept: It is a process in which addition of oxygen takes place. 2Mg + O2  →      2MgO It is a […]

Electrochemical Series and its Applications

Science > Chemistry > Electrochemistry > Electrochemical Series A series of electrodes or half cells arranged in order of their increasing standard oxidation potentials or in the decreasing order of their standard reduction potentials is called an electromotive force series or electrochemical series. Electrochemical series is also known as e.m.f. series Characteristics Electrochemical Series: In […]
