Henderson–Hasselbalch equation (video) Khan Academy

WebThe method requires knowing the concentrations of the conjugate acid-base pair and the \(K_a\) or \(K_b\) of the weak acid or weak base. However, there is a simpler method using the same information in a convenient formula, based on a rearrangement of the equilibrium equation for the dissociation of a weak acid. WebAboutTranscript. One 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. When [HA] = [A⁻], the solution pH is equal to the ...
