Fundamental Electrochemistry Is The Branch Of Chemistry That Studies The Relationship Between Electricity And Chemical Reactions. It Is A Discipline That Covers Topics Such As Electrochemical Potentials, Redox Reactions, Electrolysis, And Catalytic Processes. It Is Closely Related To Physical Chemistry As It Involves Studying The Same Fundamental Principles, Such As The Laws Of Thermodynamics And Chemical Kinetics, But It Also Applies To Understanding A Wide Range Of Organic And Inorganic Systems In A Variety Of Ways. The Physical Underlying The Fundamentals Of Electrochemistry Are The Electrochemical Potential And The Understanding Of Electrical Charge Transfer Or Oxidation-Reduction Reactions. The Electrochemical Potential Is A Measure Of The Energy Released Or Absorbed When An Electric Charge Moves From One Point In A System To Another. It Is Determined By The Relative Activities Of The Species Involved In The Reaction. A Reaction Is Said To Be A Redox Reaction When Electrical Charge Is Exchanged Between Two Species And The Species Involved Gain Or Lose Electrons. This Is Accompanied By A Concomitant Decrease In The Electrochemical Potential Across The Reaction, Resulting In Energy Released In The Form Of Heat Or Work. The Energy Released Or Absorbed During A Redox Reaction Can Be Coupled With Other Chemical Processes To Drive More Complex Reactions.
