WebHydrogen Ion Concentration. If we express the hydrogen ion concentration of an aqueous solution in relation to its molecular value we derive a scale of 1 (10 0) via 10-7 to 10-14 mole/litre. This scale is impractical but if written as a function of its negative logarithm a real and simple scale of 0 –14 has been created: the pH scale.
