Henderson-Hasselbalch Equation: Derivation and Applications

WebThe Henderson-Hasselbalch equation works best with weak acids because since weak acids dissociate only partially, there are comparable amounts of the weak acid and its conjugate base. You can use the Henderson … WebOne way to determine the pH of a buffer is by using the Henderson–Hasselbalch equation, which is pH = pKₐ + log([A⁻]/[HA]). In this equation, [HA] and [A⁻] refer to the equilibrium concentrations of the conjugate acid–base pair used to create the buffer solution. snow consulting

WebAug 4, 2016 · We can solve for the pKa by subtracting the given pKb from 14: 14 −4.75 = 9.25 Thus, your pKa is 9.25 Next, we can obtain the [base] and [acid] from the question. [N H 3]= .50 M [N H 4] =.20 M We're not really concerned with the chloride anion that attached to the ammonium ion because it's a spectator ion and it has no effect on the buffer system. WebThe Henderson–Hasselbalch equation was developed independently by the American biological chemist L. J. Henderson and the Swedish physiologist K. A. Hasselbalch, for relating the pH to the bicarbonate buffer system of the blood (see below). In its general form, the Henderson–Hasselbalch equation is a useful expression for buffer calculations.
