- pH = − log(1.75x10 − 5) + log[0.001] [0.002] = 4.76 − .30 = 4.46. Both buffers have exactly the same pH, but buffer one is clearly stronger and has 1 mole of an internal base and 2 moles of an internal acid to react with an external base or acid, while buffer two only has 0.001 and 0.002 moles respectively.
