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.
A pH value of 7 is neither acid or alkaline and is considered neutral. Pure water has a pH of 7 and is neutral. The pH scale is based on the hydrogen ions concentration [H+] in the food. The more hydrogen ions present, the more acid the food and the lower the pH.The diagram below shows the pH scale and the taste of foods at acid and alkaline pH values.he more hydrogen ions present, the more acid the food and the lower the pH. The diagram below shows the pH scale and the taste of foods at acid and alkaline pH values.
