When an acid is dissolved in water, there are more hydrogen ions(H+) present than hydroxyl ions(OH-) due to the fact that acids donate hydrogen ions. An alkaline or basic solution accepts hydrogen ions. As a result, it has more hydroxyl ions in solution. Using the pH scale, pure water is neutral with a pH of 7. Acids range from 1-6, with the strongest acid having a pH of 1. Alkaline substances range from 8-14, with 14 the value of the strongest base. When an acid is strong, like hydrochloric acid, the hydrogen ions will disassociate themselves more completely from the chlorine atoms in solution. A weaker acid will have less hydrogen ions in solution.
