The normal hydrogen ion concentration of body fluids is equal to a ph range of about 7.35-7.45. the normal hydrogen ion concentration of body fluids is equal to a ph range of about 7.35-7.45. a. true b. false

a. True The body's pH level is critical to the functioning of the bodies cells. A pH in the range of 7.35 to 7.45 is considered "normal", although a large number of doctors get nervous if the pH is towards the outer edges of that range. If your pH gets down to 6.9, you'll be a coma. At 6.8, you're dead. And if the pH goes up to 7.8, you're also dead.
