Is this what you are asking, "Will a saturated salt solution produce negative ions in the air?"

The negative ions at the bottom of the cloud also attract positive charges in the earth's surface.

However they could not contain the H in a stable way, but determined that other negative ions would do as well.

Any idea of what mechanism could produce only negative ions?

If this works as I plan it to, your city's power system will soon be flooded with negative ions.

Then the negative ions go through the wire and mix with the positive ones.

So again, I have to ask, what evidence is there that negative ions are being produced in the process?

Some people attribute this to negative ions in the air.

It is charged with negative ions which generate a feeling of well-being.

These positive and negative ions represent the charge carriers in solution.
