Anode vs Cathode: What

WebIn any voltaic cell, the cathode half cell reaction has a more positive value for Eo red. The cell potential is given by the standard reduction potential of the cathode reaction minus the standard reduction potential of the anode reaction as shown in the following equation: Eo cell = Eo red (cathode) − Eo red (anode) WebThe standard reduction potential can be determined by subtracting the standard reduction potential for the reaction occurring at the anode from the standard reduction potential for the reaction occurring at the … WebMar 10, 2024 · The EMF of the cell is the potential of the cathode subtract that of the anode, consistent with ##\Delta G = -nF\varepsilon##. If the cell is running as a galvanic cell/discharging, the EMF should be positive. If it is charging, the cathode (the one gaining electrons) is now negative and at lower potential, so the EMF should be negative. safest protein powder for weight loss
