What type of process occurs at the anode in a galvanic cell?

In a galvanic cell, the anode is the electrode where oxidation occurs. Oxidation is defined as the loss of electrons by a substance. At the anode, a chemical species loses electrons, and these electrons flow through the external circuit towards the cathode. This process is essential for generating electric current in a galvanic cell, as the anode's oxidation reaction provides the electrons needed to complete the flow of charge in the circuit.

To further clarify, during oxidation, the species at the anode typically undergoes a change in oxidation state, as it loses electrons. This is in direct contrast to what occurs at the cathode, where reduction takes place—characterized by the gain of electrons by another species. The concepts of neutralization and combustion are not relevant in this context, as they pertain to distinct chemical reactions that do not define the specific electron transfer processes occurring within a galvanic cell.
