If Ka is large and pKa is small, the substance is more willing to get rid of its hydrogen ion. So, to solve for a specific buffer's pH, one must know the pKa of the buffer's species, which can usually be found in tables. The next part, {eq}log\frac{ [Base] }{ [Acid] }...
(physical chemistry) An equation for determining the free energy of solvation of an ion in terms of the Avogadro number, the ionic valency, the ion's electronic charge, the dielectric constant of the electrolytic, and the ionic radius.
ChemistryAcids, Bases, and Salts IntroductionHenderson Hasselbalch was derived by Lawrence Joseph Henderson in 1908. The equation is used for the calculation of the pH of the buffer solution. Karl Albert Hasselbalch then in 1917 rewrote the equation in the logarithmic form. The logarithmic form of...
Carel Jan van Oss, in Interface Science and Technology, 2008 1.4 The Dupré equations What one might call the original Dupré equation for the free energy of interaction between condensed-phase materials, 1 and 2 (ΔG12), in vacuo or in air, reads as follows: (2.8)ΔG12=γ12−γ1...
In 1924, Stern made corrections to the theory accounting for the layer of counterions nearest the surface. When quantitative colloid chemistry came into existence, the “Kruyt” school (Verwey and Overbeek, 1948) routinely employed the Gouy–Chapman and Stern theories to describe the diffuse layer...
To calculate the rate of heat transfer, use the equation for the heat transfer rate through conduction. It is expressed as: Q/t =kA ((T1-T2)/l), where Q/t is the rate of heat transfer, k is the thermal conductivity of the material, A is the cross-sectional area, T1-T2 is the...
