  1. pH Notes

  2. What is pH? pH is the measure ofthe amount of free H (H+) in a solution.

  3. pH Scale Measured 1-14 1 = Highly acidic 14 = Highly basic

  4. pH Extremes Acid- an acidic solutionhas a high amount of free H+ Base- a basic solutionhas more OH- than H+

  5. Water Water has a pH of 7 NEUTRAL Means it has equalparts H+ and OH-

  6. pH Implications • Can help break moleculesdown • Can change the shapeof molecules • Can be used tocontrol body processes

  7. Buffers Weak acids and bases are used inyour body as chemicalsthat minimize drasticchanges in body pH Why?

  8. Acids + Bases =??? NaOH + HCl_______ + ________
