The pH can be calculated using Ka, the initial concentration of the acid, and its degree of dissociation. Given that cα=[H3O+],pH=pKa−log1−ααorpH=pKa+logα1−α Using the above expression, for an initial concentration (c) of acid, it is possible to calculate the proportion ...
(base dissociation constant) ionization expressions. • pK b =–logK b • The smaller K b (or larger pK b ), the weaker the base. • Two main categories of weak bases: 1. Ammonia and amines: Amines are organic compounds that, like ...
Using the surface charge density/surface potential relationship for a spherical colloidal particle with high surface potential, a simple expression for the relationship of the apparent acid constant with the degree of dissociation of surface silanol groups of silica with different sizes is derived. The...
Since lactic acid, lactate and H+ are in equilibrium defined by the acid dissociation constant KHlac (10−3.86 M): $${{{\mathrm{K}}}_{{{\mathrm{HLac}}} = \left[ {{{\mathrm{H}}}^ + } \right] \cdot \left[ {{{\mathrm{lactate}}} \right]/\left[ {{{\mathrm{lactic}}}...
Here, k¯' is the reaction rate constant in kg2/(mol2.min), Kd is the acid dissociation constant (mol/kg), Ea' is the activation energy in kJ/mol and T¯ is the reference temperature (=368.15 K). The significances and units of r, T, R, CA, CB, CC, CD and Kc are...
