Halvcellerreaksjonenes

Halvcellerreaksjonenes, also known as half-cell reactions, are a fundamental concept in electrochemistry. They describe the oxidation or reduction processes that occur at the anode and cathode of an electrochemical cell. Each half-cell reaction involves the transfer of electrons between a species in solution and an electrode. The overall electrochemical reaction is the sum of the oxidation and reduction half-cell reactions. The standard electrode potential (E°) for each half-cell reaction is a measure of its tendency to undergo oxidation or reduction. The difference in standard electrode potentials between the two half-cells determines the spontaneity of the overall reaction. Half-cell reactions are crucial for understanding and predicting the behavior of electrochemical systems, including batteries, fuel cells, and corrosion processes. They provide a basis for calculating the cell potential and understanding the thermodynamics of electrochemical reactions.
