The soil pH is a measure of the acidity or alkalinity in soils. pH is defined as the negative logarithm (base 10) of the activity of hydronium ions (H+. or, more precisely, H. 3O+. aq) in a solution. In water, it normally ranges from -1 to 14, with 7 being neutral. A pH below 7 is acidic and above 7 is alkaline.
The pH optimum of an enzyme may be very different from the normal plasma or intracellular average pH of 7.35 - 7.45; some enzymes have pH optima as low as 2 - 3, or as high as 9 - 10, and therefore little or no activity around pH 7.his graph shows the pH dependence of an enzyme that has maximum activity at pH 7.1 (i.e. an optimum pH of 7.1), and a relatively broad range of pH around that optimum at which it has activity. There would still be measurable activity at pH 6 or pH 8.
