WebbBecause pH is defined as the negative logarithm of hydrogen ion concentration (pH = −log [H +]), these values of hydrogen ion concentration correspond to a pH range of 7.35 to 7.45. Acidosis is a downward shift in pH to less than 7.35, and alkalosis is an upward shift in pH to more than 7.45. WebbThe pH of a solution is a measure of the concentration of hydrogen ions in a solution (or the number of hydronium ions). The number of hydrogen ions is a direct measure of how acidic or how basic a solution is. The pH scale is logarithmic and ranges from 0 to 14 ( Figure 2 ). We define pH=7.0 as neutral.
