WebH+ is discharged at the cathode and OH- is discharged at the anode, meaning the pH changes at both electrodes. If there is a salt bridge in this electrolytic reaction as shown in the video, would there still be a change in pH or would the salt bridge allow the solutions to mix and neutralize? Question on Electrodes: WebBelow is a picture that summarizes the cell nomenclature for a electrolytic cell. For an electrolytic cell $\mathcal{E}^\circ \lt 0 $, $\Delta G^\circ \gt 0$ Electrons flow from anode to cathode (this is always the case). For an electrolytic cell however, this flow is not spontaneous but must be driven by an external power source. In an ...
