Is it correct to say that the only ions an acidic solution contains are H+ ions and that the only ions a b?

Question

If not, what would correct descriptions of such solutions be?

Answer 1

No because a solution is acidic.(pH less than 7) does not mean that it contains H+ ions exclusively. pH is pH=1/log of the H+ ion concentration. Therefore as pH decreases H+ ion concentration increases. As pH increases OH concentration increases. a pH of 1 means that all the ions present in a solution are H+ a pH of 14 means that all the ions present are OH ions. Of course a solution could contain other ions as well. But pH is concerned primarily with H+ and OH ions.

Answer 2

By the conventional definition a solution is acidic if it has a pH less than seven, meaning a hydrogen/hydronium ion concentration greater than 1*10^-7M. The solution could potentially contain many other ions, though generally it is made up of hydrogen ions and the anion of an acid.
