Henderson-hasselbalch equation for weak base

Web4 mrt. 2024 · It is an equation used to determine the pH of a buffer solution or in our case the pH of the compartment the drug diffuses. For a weak acid the ionizing reaction is: pH … A simple buffer solution consists of a solution of an acid and a salt of the conjugate base of the acid. For example, the acid may be acetic acid and the salt may be sodium acetate. The Henderson–Hasselbalch equation relates the pH of a solution containing a mixture of the two components to the acid dissociation constant, Ka of the acid, and the concentrations of the species in solution.

WebThis volume represents one-half of the stoichiometric amount of titrant, and so one-half of the acetic acid has been neutralized to yield an equivalent amount of acetate ion. The concentrations of these conjugate acid-base partners, therefore, are equal. A convenient approach to computing the pH is use of the Henderson-Hasselbalch equation: WebThe Henderson-Hasselbalch equation also applies to a weak base.
