Electrochemistry
A sequence of lessons is devoted to the fundamental principles of electro-chemical reactions. All electro-chemical systems involve the migration of electrons within a reacting system. In many such systems, the reactions take place within a region designated as the cell, wherein the transfer of electrons is effected at the electrodes.
Balancing Oxidation-Reduction Reactions
By the conclusion of this discourse, the pupil shall be empowered to: Render a formal definition of Electro-chemistry, together with such technical nomenclature as is essential to the study thereof. Effect a partition of any given Oxidation-reduction reaction into its constituent oxidation half-reaction and reduction half-reaction. Demonstrate the production of balanced oxidation-reduction equations, whether the medium of the reaction be of an acidic or a basic character. Discern and identify with precision those substances acting as Oxidising Agents and those serving as Reducing Agents.
Galvanic Cells
By the conclusion of this discourse, the pupil shall be empowered to: Employ the proper cell notation for the formal description of Galvanic cells. Delineate the fundamental components and essential apparatus comprising the Galvanic cell.
Standard Reduction Potentials
By the conclusion of this discourse, the pupil shall be empowered to: Determine the standard cell potentials pertaining to any given oxidation-reduction reaction. Utilise the standard reduction potentials to discern which substance amongst several candidates serves as the superior Oxidising Agent or Reducing Agent.
The Nernst Equation
By the conclusion of this discourse, the pupil shall be empowered to: Establish the relation existing between the cell potentials and the changes in free energy. Employ the Nernst equation for the purpose of determining cell potentials under conditions other than the standard state. Execute such calculations as are required to effect the conversion between cell potentials, free energy changes, and the constants of chemical equilibrium.
Batteries and Fuel Cells
By the conclusion of this discourse, the pupil shall be empowered to: Classify batteries according to their nature as either primary or secondary cells. Enumerate the various characteristics and the inherent limitations pertaining to such portable sources of electromotive force. Provide a general description of the fuel cell and the manner in which it functions.
Corrosion
By the end of this section, you will be able to: Define corrosion. List some of the methods used to prevent or slow corrosion
Electrolysis
By the conclusion of this discourse, the pupil shall be empowered to: Render a description of Electrolytic cells and elucidate their relationship to those of the Galvanic variety. Execute various calculations pertaining to the phenomenon of Electrolysis.
