A short introduction to the notation of microscopic and macroscopic acidity constants of amino acids is given. The historical pathways are discussed, which led to the contemporary understanding of the acid base reactions of amino acids and their zwitterionic nature in solutions at the isoelectric point. This text is for undergraduate studies of analytical chemistry and biochemistry.
This text is written for a course on instrumental methods of quantitative analysis. It summarizes the basic concepts of modern voltammetric techniques of analysis. The guiding concept of this text is to demonstrate how the ratio of faradaic to capacitive currents decides about the sensitivity of the techniques, and how this ratio can be increased by electronics, electrode construction and by chemical...
The aim of this text is to show how the solubility (S) of metal hydroxides, oxide-hydroxides, and oxides can be calculated as function of the equilibrium pH of the solutions, taking into account the formation of various cationic and anionic species of metal aqua ions; however excluding all foreign ligands. The plots of log S versus pH are constructed and their applications to treat separations by...
Many processes and phenomena in chemistry, and generally in sciences, can be described by first-order differential equations. These equations are the most important and most frequently used to describe natural laws. Although the math is the same in all cases, the student may not always easily realize the similarities because the relevant equations appear in different topics and contain different quantities...
