A few simple facts about acids and bases will explain the reasons that pure water is a neutral substance.AcidsThe Bronsted-Lowry definition of an acid is any substance that can donate a hydrogen ion (H+).BasesThe Bronsted-Lowry definition of a base is any substance that can accept a hydrogen ion. Many bases release hydroxide ions (OH-) in solution that are attracted to hydrogen ions.pHThe acidity or basicity of a substance can be measured by its concentration of the hydrogen ion, and is represented using the pH scale. This scale ranges from 0 to 14, with acids having a pH below 7 and bases having a pH above 7.NeutralizationWhen acids and bases are combined, they neutralize each other. When an acid donates a hydrogen ion (H+) and a base donates a hydroxide ion (OH-), these two ions are attracted to each other and combine to form water (H2O).WaterPure water is a neutral substance because it combines hydrogen and hydroxide ions.
