Abstract
Students are taught that the pH of pure water is 7, but the measurement of a sample of distilled water usually gives pH values from 5.5-6.0. In addition, students learn that the ionization of a strong acid determines the pH of an aqueous solution and they cannot distinguish the cases in which ionization of water is significant. Fields of pH was developed to help students overcome such difficulties.
