<span>pHProblem 4- Determine the hydrogen concentration of bloodTutorial to help you with this calculation.<span>4.What is the approximate hydrogen ion concentration of blood with pH 7.4?</span><span> <span><span>TutorialIn this problem we are given pH and asked to solve for the hydrogen ion concentration. Using the equation, pH = − log [H+] , we can solve for [H+] as,− pH = log [H+] ,[H+] = 10−pH,by exponentiating both sides with base 10 to "undo" the common logarithm. The hydrogen ion concentration of blood with pH 7.4 is,[H+] = 10−7.4 ≈ 0.0000040 = 4.0 × 10−8 M. </span></span></span></span>
