Imagine a container of salt water at 0V (Relative to ground),Now you've put in it 2 electrodes,one at +500V (Electrode A), The other at +250V(Electrode b), Normally positive ions should go to the negative electrode , and Negative ions should go to the positive electrode , But in our example the salt water is at 0V So you would have to do positive work to go to those electrodes. But because a negative charge do a negative work to reach a higher potential, they will be attracted to both electrodes, But there would be a higher attraction for the +500V than the 250+,
My Idea is this: With more and more negative ions leaving the salt water to get dissolved in the electrodes, Salt water potential will rise until it's >250V because if salt water potential raises more than +250V positive ions will start being forced to go to the 250V electrode because it's at a lower potential, and no more negative ions will go to the +250V because they would need to do positive work to go from salt water to that electrode.
Further more I think salt water's potential will reach exactly 375V, because at this value the potential difference between Electrode A (500V) and Salt water(375V) = 125V, and the potential difference between Salt water(375V) and electrode B (250V) = 125V
So the number of positive ions that go the Electrode B is equal to the number of negative ions that go to the electrode A
