Ionic Conduction

Science > Chemistry > Electrochemistry > Ionic Conduction The conductance of an ion depends on its size in an aqueous medium or in the solvent. Bigger is the ionic size lesser is its conductance Example: The order of size of hydrated ionic radii of alkali metal cations is as Li+(aq) < Na+(aq) < K+(aq)< Rb+(aq)< Cs+(aq). Hence the ease […]

Introduction to Electrochemistry

Science > Chemistry > Electrochemistry > Introduction In this article, we shall study the concept of electrochemistry, its cause, and its terminology. Electrochemistry is a branch of chemistry which deals with the interrelationship between chemical energy and electrical energy. The study of electrochemistry is broadly divided into two branches. a) Conversion of chemical energy into […]
