Why cathode is positive in the galvanic cell? The anode is the electrode where oxidation (loss of electrons) occurs; it is the negative electrode in a galvanic cell since electrons are left on the electrode when oxidation occurs. Therefore, the cathode is a neutral electrode; because there are reduced positive ions of metal atoms. The U.S. Department of Energy's Office of Scientific and Technical Information Magnesium undergoes oxidation at the anode on the left in the figure and hydrogen ions undergo reduction at the cathode on the right. In this work, the performance of a reversible electrochemical cell using three different electrodes (Ti/Ru 0.5 Ir 0.5 O 2, Ti/Ru 0.3 Ti 0.7 O 2, and Ti/Ru 0.3 Ti 0.6 O 2 Pt 0.1) is In the figure below (from OpenStax), a copper wire is dipped in an Calculate the standard potential for this cell at 25C .
