In a voltaic galvanic cell the cathode is
WebDetermine whether each statement describes a voltaic (galvanic) electrochemical cell, an electrolytic cell, or both. Electrons move from the anode to the cathode The involved redox reaction is spontaneous. The anode is positive and the cathode is negative. The two half-reactions need to be separated in space. The cell potential is positive. WebMar 18, 2024 · There will be a slight positive charge on the cathode. In a galvanic cell, we can break apart what happens into two half reactions between the oxidized species plus an electron and the reduced species. Each of these is an equilibrium process, where we find some oxidized species and some reduced.
