Talanta, 1979
Titrimetric assays for phytic acid by titration with iron(III) or thorium are described. Stannous chloride interferes in both systems, causing negative errors directly proportional to the amount of stannous chloride. The thorium:phytate ratio in the complex formed is 2:1, which is interpreted as resulting from the possession of two chelating centres by

Titration errors in acid-base titrations
Microchemical Journal, 1990Abstract An attempt to offer a unified treatment of titration error in acid-base titrations is given in this paper. Special attention has been paid to the relationships between the titration error and the maximum sharpness index for various kinds of acid-base titrations.

Improved linear titration plots for weak-acid titrations
Talanta, 1974Linear titration plot functions are derived for the following types of titration: weak monobasic acid-strong base, weak dibasic acid-strong base weak acid-weak base. These functions are compared with the corresponding Gran functions, where possible, and the effects of the following sources of error are discussed: the neglect of activity coefficients ...

Radiometric acid-base titrations
Talanta, 1969Acid-base titrations can be performed with radiometric end-point detection by use of labelled metal salts (e.g., ZnCl(2), HgCl(2)). Owing to the formation or dissolution of the corresponding hydroxide after the equivalence point, the activity of the titrated solution linearly increases or decreases as excess of standard solution is added. The end-point

Titratable acidities of crystalline amino acid admixtures
American Journal of Health-System Pharmacy, 1980Titration curves for total parenteral nutrient (TPN) products were developed and used to determine the amount of alkali needed to make various pH changes. Equations and graphs for determining the titratable acidities of TPN solutions are presented. Samples of five crystalline amino acid products and of 1:1 mixtures of the products with 50% dextrose ...

Alternative methods for titratable acidity determination
Talanta, 1995Methods for determination of titratable acidity, other than traditional titration, i.e. methods without titration, are considered. A number of them use analytical acid-base reagents which quickly convert a mixture of strong and weak acids into a new system. This conversion makes it possible to obtain directly the analytical signal (pH, optical density,
