Open publisher page 0 citations

Abstract

The two-piont method was applied to the determination of end-point of potentiometric titration of samples of mixture containing trimetryl amine and xylidine, which is used as liquid propellant. The results of determination obtained by this method were compared with the data obtained by the arc tangent graphical method and the 2nd derivation method with t-test, showing that significant differences were not found among the data or can be corrected It was proved that the two-point method improved the potentiometric titration in easiness and rapidity in operation, in accuracy and precision and in feasibility for analysis of large number of samples.
