Arnold Beckman invented a device using a glass electrode to measure this. It can be found by replacing the reaction quotient by the activity coefficient in the Nernst equation. Often used to measure the same property as the Hammett function, it was revised in terms of activity after its definition by SÃ¸ren SÃ¸rensen. This value is computed from the log of the dissociation constant using the Henderson-Hasselbalch equation, and is roughly equal to the negative log of the concentration of H-plus ions. Estimated by litmus paper, for 10 points, name this measure of acidity with a range from 0 to 14.
