Katodová

Katodová is a Czech feminine adjective derived from katoda (cathode) and is used to describe phenomena, components, or processes associated with the cathode in electrochemical systems. The term belongs to scientific and technical vocabulary and appears in contexts ranging from chemistry and electrochemistry to electronics and corrosion protection. The gendered form follows Czech grammar, with masculine corresponding forms such as katodový and neuter katodové.

Etymology and meaning: katoda originates from the Greek kathodos, with the word entering European languages via German kathode. In Czech, katodová describes things related to the cathode, the electrode where reduction typically occurs in a galvanic or electrolytic cell, in contrast to the anode, where oxidation takes place.

Common uses: katodová reakce denotes the reduction reaction that takes place at the cathode. Katodová ochrana refers to methods of preventing metal corrosion by making the protected structure the cathode, often using an external power source or sacrificial anodes; this technique is widely applied to pipelines, ships, and underground steel structures. Katodová trubice is the Czech term for a cathode ray tube, historically used in television sets and oscilloscopes. In plating and electrolysis, katodová elektroda or katodový electrode is the electrode at which metal deposition or reduction occurs.

Notes: Katodová is typically paired with anodová to distinguish opposite electrode processes. The term appears across education, industry, and research, reflecting its central role in understanding electrode reactions and protective technologies.
