Determines the thermodynamic dissociation constant of a weak acid by potentiometric acid-base titration. Analysis of Seymour and Fernando's earlier laboratory work on the subject; Theoretical considerations regarding the titration of a weak monoprotic acid HA; Experiment designed to determine the ...
The Dissociation Constant of Acetic Acid in Water-Ethylene Carbonate MixturesHydrochloric acid solutions (0.05–1.18m) containing p-nitroaniline (8×105M) as indicator base have Ho values which increase with increase of ethylene carbonate (EC) content in the solvent mixture for a fixed molality of ...

Suppose we start with C mol L^(-1) of the weak monoprotic acid HA. Then {:(,HA,hArr,H^(+),+,A^(-)),("Initial molar conc.",C,,,),("Molar conc.",C-C alpha,,C alpha,,C alpha),("after dissociation",=C (1-alpha),,,),(,,,):} Thus, K(a) = (C alpha. C...
The dissociation of weak electrolyte (a weak base or weak acid) is expressed in terms of Ostwald's dilution law. An acid is substance which furnishes a proton or accepts an electron pair, where a base is proton acceptor or electron pair donor. Stronger is acid, weaker is its conjugate bas...
In order to elecidate the role of charge type on the change of dissociation constant with increasing polarity of the solvent medium, the p K values and associated thermodynamic quantities for an uncharged acid (acetic acid), a cationic acid (protonated tris(hydroxymethyl)aminomethane), and two ...

The variation of the acid dissociation equilibrium of trifluoromethane sulfonic acid in dilute aqueous solution along the liquidvapor dissociation curve is treated by a dielectric hydration model. The computational results indicate that the dissociation equilibrium becomes unfavorable from the point of view...
