The abbreveation used for potential hydrogen. pH represents the quantity of hydrogen ions. A measure of the acidity and alklinity of a substance; the ph scale has a range of 0 to 14, with 7 being neutral. A pH below 7 is an acidic solution; a pH above 7 is an alkaline solution. Characteristics that can be determined without a chemical reaction and that do not cause a chemical change in the substance.
It is sometimes denoted as the âPotential Hydrogen.â. For example, pure water has a pH value of 7 and is considered neutral. As the pH value lowers, the water is considered more acidic and as it elevates above 7 it is considered more alkaline. Standards for drinking water suggest a pH value of between 6.5 and 8.5.
