Catalytic and Differential Rate Methods

Abstract

I. PREFACE Although kinetics has enjoyed a recognized place in most of the other traditional subdisciplines of chemistry (inorganic, organic, and physical), it has been somewhat ignored in chemical analysis. In an analytical methodology dominated by measurements at equilibrium or in systems in which time is not a variable of importance, kinetics has been considered mainly in the context of undesirable effects, such as the sluggishness of some end-points obtained with color indicators in redox titrimetry. As a result of this, it is not surprising that textbooks in analytical chemistry have been dominated by the equilibrium view of chemical analysis, and only recently have some of them1 turned their attention to kinetics and its application to analytical determinations. An exception to this trend is the fourth edition of what may be considered one of the most ‘classical’ textbooks on quantitative analysis, that of Kolthoff and Sandell. Although in the third edition2 catalytic methods are briefly mentioned i...
