WebThe concentration of hydrogen ions can vary across many orders of magnitude—from 1 to 0.00000000000001 moles per liter—and we express acidity on a logarithmic scale called the pH scale. Because the pH scale is logarithmic (pH = -log [H + ]), a change of one pH unit corresponds to a ten-fold change in hydrogen ion concentration (Figure 1).
