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).

Potentiometric titration of lignosulfonic acids

Russian Journal of Applied Chemistry, 2008
The conditions of potentiometric titration of lignosulfonic acids allowing quantitative determination of strongly and weakly acidic functional groups in lignosulfonates were determined.

Acid-Base Titration Curves

2012
The theoretical study of titration curves is necessary because it allows us, among other things, to choose the optimal conditions for detecting the equivalence point in order to minimize the titration error.

Logarithmic diagrams in acid—base titrations and estimation of titration errors

Talanta, 1980
The use of a logarithmic diagram for the estimation of the pH-value at the equivalence point and the titration error when a solution containing one or two acids is titrated with standard alkali is described.

Acid—Base Titration Curves

1975
The familiar curves of pH versus volume of titrant added are displayed and discussed in many texts. Here we shall examine only a few mathematical aspects which follow from our previous treatment and which bear upon the reliability of the end point determination.

Scandium-ethylenediamine tetraacetic acid titrations

Microchemical Journal, 1965
Summary Complexometric determinations of scandium with Alizarine Red S, thoron, and Murexide as chelatochromic indicators have been reported. The effect of pH on the titer value, the range of concentration, and the interferences due to foreign ions have been studied in detail.
