Acids produce (positive or negative) ions in water and bases produce (positive or negative) ions in water. Thanks for helping with this.
It all depends upon how acids and bases are defined. Some acids and/or bases don't have water at all.
If you are dealing with the Arrhenius theory of acids and bases, then I suppose acids produce positive ions (but not just ANY positive ion---they must be H^+) and bases produce negative ions (but not just ANY negative ions---just OH^-). If this is a question that you have been given to find the answer, my opinion is that it's is a poor question. I think you should have a "none of these" as a choice.
