hydrogen ion concentration

[′hī·drə·jən ′ī‚än ‚käns·ən‚trā·shən]
(chemistry)
The normality of a solution with respect to hydrogen ions, H+; it is related to acidity measurements in most cases by pH = log 1/2 [1/(H+)], where (H+) is the hydrogen ion concentration in gram equivalents per liter of solution.
