Henderson hasselberg equation
WebEcuación de Henderson-Hasselbalch. La ecuación de Henderson-Hasselbalch es una expresión utilizada en química para calcular el pH de una disolución reguladora, o también, a partir del p Ka o el p Kb (obtenidos de la constante de disociación del ácido o de la constante de disociación de la base) y de las concentraciones de equilibrio ... 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 …
