WebThe Henderson-Hasselbalch equation is derived from this acid ionization constant. Note that is a weak acid. By definition, does not dissociate completely and we can say and . Hence, we can use the initial concentrations because Simillarly, for a weak base and its conjugate acid : which has an base ionization constant ... WebFeb 7, 2024 · The Henderson-Hasselbalch equation is a mathematical expression used to find out the pH of buffer solutions. This equation relates pH, dissociation of a weak acid, and the ratio of the concentrations of its salt of the conjugate base and the concentration of acid. The equation is as follows: where, pH is the negative log of H + ions concentration.
