Yes.
Yes, it is ionised as after ionisation of hydrogen and oxygen only water is formed.
De-ionised water is normally known as demineralised water. It?æis water whose mineral ions such as calcium, sodium and iron has been removed.
Distilled water, or de-ionised water would be used in a laboratory.

Yes. There is no benefit to drinking "oxygenated" water.
distilled water refers to water nearly free of ionised atoms such as Cl,Mg,and Na
every gas can be ionised, in fact, any chemical can be ionised.
De-ionised water Distilled water is recommended if the battery just needs topping off. Sulfuric acid if the battery is empty.
Entirely free of salts = distilled or de-ionised water. However in general terms "fresh" water is regarded to be salt free while "sea" water contains salt.
It is not possible.
No. not earthly vehicles. Some spacecraft have ion engines (at least they have been proposed).
