Henderson-Hasselbalch equation a formula for calculating the pH of a buffer solution such as blood plasma, pH = pKa + log [BA/HA]; [HA] is the concentration of a free weak acid; [BA] the concentration of the ionized form of this acid; pKa the acid dissociation constant, a measure of...
What equation is used for calculating the pH of an acid buffer? To calculate the pH of an acid buffer, the Henderson-Hasselbalch equation is used, which is pH = pKa + log(acid/base). The acid's concentration is on top of the fraction, and the conjugate base's is on the bottom. Wh...

A better approach for calculating these parameters is to determine energies of activation from kinetic studies (see Chapter 7). Some investigators have also employed a two-site or two-surface Langmuir equation to describe sorption data for an adsorbent with two sites of different affinities. This ...

This equation referring to a particle pair has the same form as (7.11) quoted previously for the Brownian motion of a single particle. The quantity (kT)/(2mγ) is, according to (7.13), interpretable as a diffusion coefficient for the pair motion. By calculating the non-equilibrium configurat...
Discover the Henderson-Hasselbalch equation for calculating pH of buffers—unravel its formulation, understand the ionization constant of a weak acid, and how it links pH with concentrations of a weak conjugate acid-base pair. Start mastering buffer chem
The calculation of thermodynamic properties for alkanes up to squalane is possible with both approaches, for some of which no highly accurate fundamental equation of state is available in the literature. For the first approach, the original parameter set was refitted with constraints guaranteeing ...
The Clausius-Clapeyron equation may be used for calculating any of the quantities entering into the equation if the remaining quantities are known. In particular, the equation is used for calculating the heats of evaporation, which are difficult to determine experimentally. ...
The theoretical titration curve of a weak acid with a strong base was considered. The limitation of the Henderson-Hasselbalch equation for the calculation of pH in the buffer region was discussed. One novel simple equation for the exact calculation of pH
