Titration curves for the acid—base–titration of polyvalent acids and bases and their mixtures can be created in a simple way and presented graphically. The method, an alternative to the existing procedures, shall be presented here for discussion. With the described method it is possible in an...
The equations useful for searching the inflection points on titration curves are derived. A kind of "homogenization" of complex acid-base systems, with polyprotic acids with defined and/or undefined (e.g., fulvic acids) composition, with use of an approach based on Simms constants principle, ...

The acid–base titration curves of three wools, Merino, Yankasa, and a ⅝–⅜ Merino–Yankasa crossbred wool, grown in Nigeria, were measured at 25°C in the presence of varying amounts of sodium chloride. Amino acid analysis was carried out on these wools and correlated with the acid...
In the description of acid-base titrations a general master equation is developed. It provides a continuous and complete description of the entire titration curve, which can then be used for computer-based comparison with experimental data. Graphical estimates of the steepness of titration curves ...
