Products of Electrolysis
Products of Electrolysis During electrolysis, the reactions occurring at the electrodes are oxidation and reduction reactions. The products of electrolysis depend on the nature of material being electrolysed and the types of electrodes being used. If the electrode is inert such as gold or platinum, it does not take part in the chemical reaction and acts only as a source or … [Read more...] about Products of Electrolysis
Electrolytic Cells
Electrolytic cells Electrolysis is a process in which chemical changes take place by the passage of electric current. The cells used to carry out electrolysis are electrolytic cells Process of electrolysis 1) The process of electrolysis is carried out by taking the solution of an electrolyte in a suitable vessel. The vessel is called electrolytic tank. 2) It is made … [Read more...] about Electrolytic Cells
Nernst Equation
Nernst Equation The standard electrode potentials are measured in their standard states when the concentration of the electrolyte solutions are fixed as 1M and temperature is 298 K. In actual practice electrochemical cells do not have always fixed concentration of the electrolyte solutions. The electrode potentials depend on the concentration of the electrolyte solutions. … [Read more...] about Nernst Equation
Electrochemical Series
Electrochemical Series The arrangement of elements in order of increasing electrode potential values is called electrochemical series. The electrochemical series is also called the activity series. Applications of the Electrochemical Series The main applications of the electrochemical series are: 1) Relative Strengths of Oxidising and Reducing Agents In the … [Read more...] about Electrochemical Series
