pH is a measure of the acidity or basicity of a solution.
It is defined as the cologarithm of the activity of
dissolved hydrogen ions (H+). Hydrogen ion activity
coefficients cannot be measured experimentally, so they are
based on theoretical calculations. The pH scale is not an
absolute scale; it is relative to a set of standard
solutions whose pH is established by international
agreement.
Pure water is said to be neutral. The pH for pure water at
25 °C (77 °F) is close to 7.0. Solutions with a pH less
than 7 are said to be acidic and solutions with a pH
greater than 7 are said to be basic or alkaline. pH
measurements are important in medicine, biology, chemistry,
food science, environmental science, oceanography and many
other applications.
