Quizplus · Accepted Answer

The pH of blood primarily depends upon a normal concentration of hydrogen ions. The normal pH of arterial blood is in a range of 7.35-7.45, which is slightly alkaline. The concentration of hydrogen ions determines the acidity or alkalinity of the blood. Too many hydrogen ions result in acidosis, and too few hydrogen ions result in alkalosis. Therefore, the normal concentration of hydrogen ions plays a crucial role in regulating the pH of the blood.
