For example : Pepsin has an optimum of pH 2.5 and a working range of between pH 1-4. Catalase has an optimum pH of 9 and a working range of between pH 7-11. Most other enzymes function within a working pH range of about pH 5-9 with neutral pH 7 being the optimum.

WebbExample. Thus, the pH of an acidic solution of HNO 3 (10 –3 M) = 3, a basic solution of KOH having [OH –] =10 –4 M and [H 3 O +] =10 –10 M will have a pH = 10. pH of acids is … WebbThe normal extracellular pH is generally in the range of 7.4. Elevated blood hydrogen ion levels (pH <7.4) are described as an acidemia, and reduced hydrogen ion levels (pH >7.4) are described as an alkalemia.1. There is a widely held misunderstanding that the body regulates hydrogen ion concentration within very narrow limits.
