Ask current analytical chemistry faculty what
textbook they had for their Quantitative Analysis course way
back when, and you are likely to get one of two responses:
Skoog, West, and Holler's Fundamentals of Analytical
Chemistry or Analytical Chemistry: An
Introduction, which first appeared in 1963 and 1965, respectively, or Daniel C. Harris's
Quantitative Chemical Analysis, which was introduced in 1982. Skoog et
al. offer solid fundamentals, somewhat dated literature
references, and straightforward experiments that are perfect for
developing and assessing lab technique. Harris incorporates
much of the same material, but adds relevance with examples
from the current and not-too-distant literature. Unlike
Skoog's dry, no-nonsense style, Harris's style is more
conversational. Experiments for technique are available, as well as
ones providing a sense of how analytical chemistry can be
applied to biological or environmental problems. Both texts
offer spreadsheet exercises for handling repetitive calculations
and for the graphical analysis of data.
For a new quantitative analysis textbook to
compete against the established two, it must offer something more
than just a different writing style, an extra topic, or nicer
color plates. Instead, it should better reflect analytical
chemistry as it is practiced today. David Harvey's
Modern Analytical Chemistry is a new textbook that nicely fills the bill. The
same size as other texts, it is organized into only 15 chapters.
None of the chapters are incomplete and as a result, some run
to 90 pages in length. All the expected topics are present
and are found in roughly the same order used by Skoog et
al. and Harris. Three notable content differences are the
inclusion of ladder diagrams for evaluating equilibria, a chapter
on kinetic methods of analysis, and a chapter on developing
a standard method. Much of the material in the kinetic
methods chapter is also likely to be covered in a physical
chemistry course, but the section on flow injection analysis is
certainly applicable to the quantitative analysis curriculum. The
chapter on developing a standard method completes the
calibration/ standardization chapter (which is found much earlier in
the text) by answering the question of how a method for
analysis is actually developed and evaluated.
Content differences aside, there are other features
in Modern Analytical Chemistry that make it quite attractive.
First, concepts are presented with clear explanations in a
relaxed, conversational writing style. Students reading the text
should find it accessible and uncluttered. Material is supported by
a respectable number of problems at the end of the
chapter. Many of the exercises Harvey has provided are word
problems derived from published work and they require students
to think, not just "plug and chug", to get the correct answer.
The solutions manual is complete and provides excellent
coaching on each step involved in arriving at the final answer.
Literature references are incorporated into the text and are for the
most part very current. Each chapter also has a fairly extensive list
of suggested readings, which are nicely divided between
journals and books. The inclusion of a significant number of
articles from the Journal of Chemical
Education should make it possible to send students to the literature with the expectation
that what they find will be written in such a way that they
can make use of it.
One challenge to writing a quantitative analysis textbook
is trying to provide laboratory activities that are useful
to the instructor. Each institution has different
enrollments, facilities, and roles for the quantitative analysis
laboratory. Rather than present just one or two experiments,
Harvey provides 10 to 20 suggestions at the end of each chapter,
drawn almost exclusively from the Journal of Chemical
Education. Choosing from this large number is simplified by the
summary of each experiment found after the citation. Like the strong
list of references and suggested readings, the listing of
experiments provides an excellent means of getting students into
the literature.
If Modern Analytical
Chemistry has a drawback, it is the decision to use only 15 chapters to present the material.
While it does make sense to place all of chemical equilibrium,
spectroscopic methods, electrochemistry, separations, etc.
into single chapters, there is a certain psychological effect of
taking on a 90-page chapter. My concern is for the typical
student, who waits until the end and only then realizes what a
single chapter means in terms of material for an exam or
quiz. Otherwise, David Harvey has done a very nice job in
developing a textbook that has something new to offer to
both faculty and students interested in studying the
fundamentals used when practicing analytical chemistry today.
