In the context of a couple forming a cell, which two electrodes are specified?

In a galvanic cell, the electrodes have specific roles defined by their functions during chemical reactions. In this context, the anode and cathode are essential in establishing the flow of electrons, which is a fundamental aspect of electrochemistry.

The anode is where oxidation occurs, meaning it is the electrode that loses electrons, while the cathode is where reduction takes place, involving the gain of electrons. Together, these two electrodes facilitate the flow of current and allow for the conversion of chemical energy into electrical energy.

Understanding the roles of the anode and cathode clarifies the processes occurring within the cell, which is critical in the study of thermochemistry and electrochemical reactions. The right-hand and left-hand electrodes or terms like active and passive do not convey the specific electrochemical functions, while standard and measuring electrodes are more relevant in different experimental contexts, such as calibration and electrochemical measurement. The distinction between anode and cathode is foundational in understanding cell operations and electron flow.
