So for both voltaic and electrolytic, electrons flow from anode to cathode, and oxidation occurs at the anode and reduction at the cathode. Also anions flow to the anode and cations to the cathode.
Both for voltaic, since the electrons flow from the anode to the cathode, the anode is negatively charged and the cathode is positively charged? (this is how TPR reasons it). Thus anode is electron deficient, so it is more positive for the anions to flow to and cathode is more negative for the cations to flow to?
And in a electrolytic cell, electrons are pumped by the battery so the anode is positively charged and cathode is negative? But then what are the ions doing.. I'm pretty sure it's still anions to anode and cations to cathode.
The review books are vague regarding this, so some clarification would be great.
Oh and also, the salt bridge allows for the flow of ions to complete complete the circuit correct? So without the salt bridge, there would be no constant current flow? And if there wasn't one, it would essentially be a capacitor in a sense?
