Anodischer

Anodischer is a German adjective derived from Anode, used in electrochemistry and related technical fields to denote relation to the anode, the electrode at which oxidation occurs. The closest English equivalents are anodic or anode-related. In electrochemical cells, the anode is the site of oxidation; its electrochemical role depends on the cell type: in galvanic (discharging) cells the anode is negative, while in electrolytic (charging) cells it is positive. The term anodischer describes phenomena tied to this electrode or its potential, such as anodischer Prozess (anodic process), anodische Reaktionen, or anodische Oxidation.

Common examples include metal dissolution at the anode, evolution of oxygen in aqueous solutions, and the formation of oxide films by anodization. Anodization is a controlled electrochemical oxidation used to create protective oxide layers on metals such as aluminum, titanium, and niobium; in these processes the metal surface acts as the anode in an electrolytic cell.

In broader usage, anodischer context appears in topics like corrosion protection, where anodic protection aims to maintain the metal surface at an anodic potential to reduce corrosion, and in analytical chemistry, where anodic processes are exploited in techniques such as anodic stripping voltammetry to probe oxidation at the electrode. While primarily encountered in German-language texts, the term aligns closely with the English anodic and provides a concise descriptor for electrode-related phenomena.
