Katodeissa

Katodeissa is a Finnish term that translates to "in the cathodes" or "at the cathodes." It refers to the location or state of being within or at the cathode of an electrochemical cell. A cathode is the electrode where reduction occurs, meaning it is the site where electrons are gained by a species. In an electrolytic cell, the cathode is the negative electrode, and it attracts positive ions (cations) from the electrolyte, which then accept electrons and are reduced. In a galvanic cell (like a battery), the cathode is the positive electrode, and it is where the reduction half-reaction takes place, consuming electrons. The specific chemical processes occurring at the cathode depend entirely on the type of electrochemical cell and the species present in the electrolyte. Therefore, "katodeissa" signifies participation in or observation of these electron-accepting processes within an electrochemical system.
