To solve the problem of finding the equilibrium constant for the reaction of a weak acid with a strong base given that the dissociation constant (Ka) of the weak acid is 10−6, we can follow these steps: Step 1: Write the dissociation reaction of the weak acid.Let’s denote the weak...
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...
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 ...

Note that the percent dissocaition can be solved using Percent Dissociation=[H+][HA]⋅100%. In the case of a weak acid standard reaction given as HA↔H++A−, where HA is the weak acid, the ionization constant (Ka) can determined via Ka=[H+][A−]...
A method is described for computing the dissociation constant and equivalent conductance at infinite dilution, Ao , for a weak electrolyte from as few as two conductance measurements at different concentrations. The iterative procedure applied to acetic acid data yielded a dissociation constant of 1.80...
