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 ...

For, in mathematics or symbolic logic, reason can crank out the answer from the symboled equations—even a calculating machine can often do so—but it cannot alone set up the equations. Imagination resides in the words which define and connect the symbols—subtract them from the most aridly ...
The result of integrating a scalar field along a given curve is important for calculating many physical quantities. We know that in one dimension we relate the work done by a force in moving from one location to another as W = ∫ F dx, where F is the force, W is the work done or ...
the formula for calculating the pH of a buffer solution, which states that: where pK is the dissociation constant of an acid. The variable term is really a ratio of concentration values and can be taken as being proportional to the amount of acid and base added in the buffer. For exampl...
In 1909, Danish biochemist Søren Peter Lauritz Sørense proposed the following equation forcalculating pH: pH = -log[H+] where log is the base-10 logarithm and [H+] stands for the hydrogen ion concentration in units of moles per liter solution. The term "pH" comes from the German w...
