In its general form, the Henderson–Hasselbalch equation is a useful expression for buffer calculations. It can be derived from the equilibrium constant expression for a dissociation reaction of the general weak acid (HA) in Equation (): ()K=[H+][A-][HA] where K is . Jan 28, · The Henderson-Hasselbalch equation (Equation \(\ref{HH}\)) is an approximation, with a certain region of validity. By its nature, it does not take into account the self-dissociation of water, which becomes increasingly important in dilute solutions. Sep 25, · Henderson-Hasselbalch Equation. The Henderson-Hasselbalch equation relates pH, pKa, and molar concentration (concentration in units of moles per liter): pH = pKa + log ([A-]/[HA]) [A-] = molar concentration of a conjugate base. [HA] = molar concentration of a undissociated weak acid (M) The equation can be rewritten to solve for pOH.

Derivation of the Henderson-Hasselbalch equation. Created by Sal Khan. Watch th Author: Khan Academy. Lawrence Joseph Henderson and Karl Albert Hasselbalch. Lawrence Joseph Henderson () was a talented biochemist, among many other titles, who spent most of his career at Harvard. He was responsible for developing the components of the equation after studying equilibrium reactions that took place within blood as a result of respiration (specializing in "fatigue"). Buffers and the Henderson-Hasselbalch Equation Problems #31 - (a) the blood (pH = ) (b) the stomach (pH = ) General comment about the solutions: You have to find the ratio between A¯ and HA so the concentrations are not needed Solution to part (a).

[HA] = molar concentration of a undissociated weak acid (M) The equation can be rewritten to solve for pOH. The Henderson-Hasselbalch equation describes the relationship of pH as a measure of acidity with the acid dissociation constant (pKa), in biological and chemical systems. The equation is especially useful for estimating the pH of a buffer solution and finding the equilibrium pH in acid-base reactions.
In my opinion it is not logical
