Definition of Ph

1. Noun. (from potential of Hydrogen) the logarithm of the reciprocal of hydrogen-ion concentration in gram atoms per liter; provides a measure on a scale from 0 to 14 of the acidity or alkalinity of a solution (where 7 is neutral and greater than 7 is more basic and less than 7 is more acidic).

Medical Definition of Ph

1. The symbol relating the hydrogen ion concentration or activity of a solution to that of a given standard solution. Numerically the pH is approximately equal to the negative logarithm of hydrogen ion concentration expressed in molarity. PH 7 is neutral, above 7 is alkaline and below is acidic.
