Dear John F.,
It appears that you haven't framed these questions well, they're like asking, out of the blue, "What direction is the camel facing?". Did you leave out some info, perhaps?
Assuming you have some NaCl and some NaOH in your solution? Then you're asking if the OH- could exist at that level. If the Na+ can live at 13.9M, the OH- will be comfortable. But no way you'll get NaCl dissolved at that concentration, to make up the rest; it only dissolves maybe 5M. So, no way!
And about separating atoms of Na and Cl in water: they only exist there as Na+ and Cl- . And you can't separate them in the sense of getting them all into two compartments. Electrostatic forces would prevent that. They are separated, somewhat, by being surrounded by water molecules. But you didn't do that, the water did.
Hope this helps you a bit, -- Mr. d.
