Question

A liquid has a oh of 7.4, find the hydrogen ion concentration [H+]?

Answer 1

pHProblem 4- Determine the hydrogen concentration of bloodTutorial to help you with this calculation.4.What is the approximate hydrogen ion concentration of blood with pH 7.4? 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.
