Courtesy of USGS Biology, Contaminant Biology Program Because pH is a logarithmic function, one unit change in pH (e.g., 7 to 6) indicates a 10x change in H + concentration in that solution. However, what is actually measured is hydrogen ion activity, not concentration. WebThe pH scale is logarithmic, meaning that an increase or decrease of an integer value changes the concentration by a tenfold. For example, a pH of 3 is ten times more acidic than a pH of 4. Likewise, a pH of 3 is one hundred times more acidic than a pH of 5. Similarly a pH of 11 is ten times more basic than a pH of 10.
