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 ...
where dissociation is complete , However, it is a weak acid where dissociation is partial, the dissociated is low, the actual pH would be higher than 1.12 .OR, dissociation of acid is not complete, it is a weak acid.(iii)(iv)When of is added, half of the weak acid would have react...
Answer to: A 0.0700 M solution of a weak acid (HA) was found to give a pH of 4.9. What is the dissociation constant (Ka) of the acid? By signing...

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 ...
Dissociation constant of a weak acid is decreased by AAddition of a strong acid BAddition of a salt of the above weak acid CDecreasing temperature DDilution of the solutionSubmit The dissociation of weak electrolyte (a weak base or weak acid) id expressed in terms of Ostwald dilution law....
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−]...
