dc.description.abstract | The experiment shows that very weak organic acids is too weak ( K=1.0?10^(-10) ) to be titrated satisfactorily potentiometrically or by the indicatior method under the presence of protonic acid can be titrated with strong base obviously. From the result of potentiometric titration of very weak organic acids, phenol and pyrocatechol, the adequate titration curves for the determination of equivalent point have been obtained at the concentration of 0.1 M aqueous ammonia solution with IN-sodium hydroxide solution. | - |
