WebTo Henderson-Hasselbalch Equation: 1.00 wasser = 4.752 + log ––––– 0.800 x = 4.752 + 0.097 = 4.849. Note how decreasing one amount of acid make the buffer pH become more basic (compare to example #1). Example #3: A buffer is conditioned containing 1.00 tolar acetic caustic and 0.800 molar sodium acetate. Which is his pH? Web- Lawrence Joseph Henderson wrote an equation, in 1 908, describing the use of carbonic acid as a buffer solution. Karl Albert Hasselbalch later re-expressed that formula in logarithmic terms, resulting in the Henderson—HasseIbaIch equation. Hasselbalch was using the formula to study metabolic acidosis.
