Yes, you cannot have an anion without a corresponding cation, and vice versa.

2Ag+ would most likely actually be the dissolved compound of silver oxide.

They keep ions apart.

Anything above Ag2+ would be a charged particle, not necessarily an ion.  That
starts really getting confusing, especially since we all know that a particle
of silver that is charged should be positive, but according to Frank Key the
zeta measures negative.  That is presumably due to OH- radicals from the water
surrounding the particle, and canceling out the positive charge, yet being
around the particle making the whole thing look slightly negative.

I am not really sure exactly what is going on here, but it really isn't silver
hydroxide since it will not dissolve into water no matter how much you dilute
it.
