Web30 jan. 2015 · As a result, pH is a measure of hydrogen ion activity. If the activity coefficient is determined to be 0.91 and the hydrogen ion concentration is 100 mol/kg*, the ion activity would be equal to 91. *Although ion activity and the activity coefficient have no units, their magnitude depends on the concentration units used. WebAt a neutral pH of 7 (pure water), the concentration of both H+ ions and OH- ions is 10⁻⁷ M. Thus the ions H+ and OH- are always paired – as the concentration of one increases, the other will decrease; regardless of pH, the sum of the ions will always equal 10⁻¹⁴ M ². high purine fruits and vegetables
