12.3 The pH Scale and pH Calculations | High School Chemistry

In this lesson Chad introduces the pH scale and shows how to perform pH calculations. This includes a description of the autoionization of water explaining the presence of H+ and OH- present in aqueous solutions. pH and pOH are clearly defined and the mathematical relationships between [H+], pH, [OH-], and pOH are established with the accompanying calculations. Finally, the lesson is concluded with a description of how to calculate the pH of strong acids and strong bases with several examples of each performed.
