Titration errors in acid-base titrations

Microchemical Journal, 1990
Abstract 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, 1974
Linear 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 ...

Thermometric titration of acids in pyridine

Talanta, 1974
Thermometric titration of HClO(4), HI, HNO(3), HBr, picric acid o-nitrobenzoic acid, 2,4- and 2,5-dinitrophenol, acetic acid and benzoic acid have been attempted in pyridine as solvent, using 1,3-diphenylguanidine as the base. Except in the case of 2,5-dinitrophenol, acetic acid and benzoic acid, the results are, in general, reasonably satisfactory ...

Radiometric acid-base titrations

Talanta, 1969
Acid-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, 1980
Titration 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 ...

Titration of Mixtures of Acids

Nature, 1957
THE determination of the degree of polymerization of polyamides or polypeptides by end-group titration is, in effect, a determination of the amount of the weakly acidic carboxyl group (dissociation constant K 2) in presence of a large excess of the base of a stronger acid, the amide or peptide group (dissociation constant K 1).

Acid–Base Titration

The Chemical Educator, 2002
Phosphoric acid anodizing solutions are routinely titrated to monitor their concentrations; however, after successive anodizations of aluminum metal, increasing amounts of dissolved aluminum interfere with the neutralization titration. The true concentration of phosphoric acid is determined by a correction factor based on the concentration of the ...

Titration of Acids and Beverages Using a Conductivity Titrator

Korean Science Education Society for the Gifted
The beverages contain acids such as citric acid, vitamin C, and phosphoric acid, in addition to sugar, which contribute to their sour taste. In this study, an acid–base titration was performed using a conductivity titrator to conduct both quantitative and qualitative analyses of the acids present in beverages. Conductivity is proportional to the number

Titration of adsorbed acids

Recueil des Travaux Chimiques des Pays-Bas, 1948
AbstractThe researches here described deal with electrometric titrations of strong acids in the presence of adsorption charcoal (Norit). The titration curves of the system containing charcoal are of the type of titration curves of weak acids; the systems have a pronounced buffer capacity.
