Notes pH  Key Questions pH scale- indicates the concentration of H+ ions in solution. pH scale ranges from 0 to 14 Acids have high concentrations of H+ ; pH values scale below 7. Bases have low concentrations of H+ ; pH values above 7. Controlling pH is important for maintaining homeostasis because almost all enzymes within the body function at a specific pH. pH of the fluids within most cells in the human body must generally be kept between 6.5 and 7.5.
