Acidity in a solution such as rain is synonymous with the presence of hydrogen ions (H+). A common measure of acidity is pH ... The pH scale ranges from 0 to 14, with a value of 7 representing a solution is neutral, values below 7 indicating greater acidity and values above 7 indicating greater alkalinity. One should bear in mind that the pH scale is logarithmic, so that solutions of PH 6, 5 and 4 contain respectively one, 10 and 100 microequivalents of acidity (H+) per liter (abbreviated µeq/l).
