The format encourages students to think about the design of the procedure and why it works. Modern Analytical Chemistry An additional problem is encountered when the isolated solid is nonstoichiometric. In this case the nonstoichiometric product results from the formation of a mixture of several oxides that differ in the oxidation state of manganese. Other nonstoichiometric compounds form as a result of lattice defects in the crystal structure. Representative Methods Representative Method The best way to appreciate the importance of the theoretical and practical details discussed in the previous section is to carefully examine the procedure for a typical precipitation gravimetric method. Calcium, which is the most significant interferent, is usually removed by its prior precipitation as the oxalate. The presence of excess ammonium salts from the precipitant or the addition of too much ammonia can lead to the formation of Mg NH4 4 PO4 2, which is subsequently isolated as Mg PO3 2 after drying. The precipitate is isolated by filtration using a rinse solution of dilute ammonia. After filtering, the precipitate is converted to Mg2P2O7 and weighed. Add 2—3 drops of methyl red indicator, and, if necessary, adjust the volume to mL. After stirring for 5 min, add 5 mL of concentrated NH3, and continue stirring for an additional 10 min. Allow the resulting solution and precipitate to stand overnight.

The text doesn't assume the reader has previous knowledge of technical terminology and describes such things effectively. Consistency rating: 5 The text provides chapters on a general chemistry review of topics, analytical vocabulary, and statistical methods that provide a foundation consistently used throughout the text. No issues here. Modularity rating: 5 This is probably the best part of the text, and what makes it ideal for an undergraduate analytical chemistry course.

The text is broken down logically with each topic comprehensive yet succinct. The chapters build within themselves effectively, and are organized into "bite-sized" pieces that are, once again, perfect for undergraduate consumption.

If I could change one thing I would put the kinetic review in the actual chapter as opposed to an appendix. While yes this SHOULD be a review from general chemistry in my experience students will not access information that isn't directly put into the chapter. While I could certainly try and force them to go to back of the book, it just seems unnecessary to add a short appendix when the information could be put into the chapter and only add a couple of pages.

This is especially true within each chapter where the flow of topics build upon one another exceptionally. It's possible the author wanted it to be right before the text transitions to methods of analysis, but I'd introduce it earlier in my class.

You could make a similar argument for developing a standard method, that it should be introduced earlier in the text maybe before chapters , however the way it is written relies on knowledge from the previous chapters for student clarity and understanding. I really like the idea of the chapter, as well as the content, but wish it was written to be chapter 8 instead of This will make it difficult to get to in the curriculum and may delegate it to a second semester course such as Instrumental.

Interface rating: 5 Figures, images, and text were all crisp and clear. No issues navigating throughout the text. There are some minor editing issues see chapter 4 in the table of contents but they don't seem to be related to any display problems.

Grammatical Errors rating: 3 A score of "3" is probably a bit harsh, as the text overall is well-written, but there were a number of noticeable grammatical errors in the text. These ranged from misspelled words to subject-verb disagreements or the use of singular versus plural nouns.

For example, as described in this chapter, a solution of These exercises also provide practice with using volumetric glassware, weighing samples, and preparing solutions. References The references cited in the chapter are provided so the student can access them for further information.

When working with a solid sample, it often is necessary to bring the analyte into solution by dissolving the sample in a suitable solvent. Any solid impurities that remain are removed by filtration before continuing with the analysis. In a typical total analysis method, the procedure might read After dissolving the sample in a beaker, remove any solid impurities by passing the solution containing the analyte through filter paper, collecting the solution in a clean Erlenmeyer flask.

Rinse the beaker with several small portions of solvent, passing these rinsings through the filter paper, and collecting them in the same Erlenmeyer flask. Finally, rinse the filter paper with several portions of solvent, collecting the rinsings in the same Erlenmeyer flask.

For a typical concentration method, however, the procedure might state Standardization—External standards, standard additions, and internal standards are a common feature of many quantitative analyses. Suggested experiments using these standardization methods are found in later chapters. Results can be compared with those The role of analytical chemistry within the broader discipline of obtained using a standard addition.

Problems A variety of problems, many based on data from the analytical literature, provide the student with practical examples of current research. Analytical chemistry, however, is more than equilibrium chemistry and a collection of analytical methods; it is an approach to solving chemical problems.

Although discussing different methods is important, that discussion should not come at the expense of other equally important topics. The introductory analytical course is the ideal place in the chemistry curriculum to explore topics such as experimental design, sampling, calibration strategies, standardization, optimization, statistics, and the validation of experimental results.

These topics are important in developing good experimental protocols, and in interpreting experimental results. If chemistry is truly an experimental science, then it is essential that all chemistry students understand how these topics relate to the experiments they conduct in other chemistry courses.

Currently available textbooks do a good job of covering the diverse range of wet and instrumental analysis techniques available to chemists. Although there is some disagreement about the proper balance between wet analytical techniques, such as gravimetry and titrimetry, and instrumental analysis techniques, such as spectrophotometry, all currently available textbooks cover a reasonable variety of techniques.

These textbooks, however, neglect, or give only brief consideration to, obtaining representative samples, handling interferents, optimizing methods, analyzing data, validating data, and ensuring that data are collected under a state of statistical control.

The anticipated audience for this textbook includes students majoring in chemistry, and students majoring in other science disciplines biology, biochemistry, environmental science, engineering, and geology, to name a few , interested in obtaining a stronger background in chemical analysis. It is particularly appropriate for chemistry majors who are not planning to attend graduate school, and who often do not enroll in those advanced courses in analytical chemistry that require physical chemistry as a pre-requisite.

Prior coursework of a year of general chemistry is assumed. Methods for characterizing chemical measurements, results, and errors including the propagation of errors are included. Both the binomial distribution and normal distribution are presented, and the idea of a confidence interval is developed. Statistical methods for evaluating data include the t-test both for paired and unpaired data , the F-test, and the treatment of outliers.

Detection limits also are discussed from a statistical perspective. Selecting the most appropriate calibration method is important and, for this reason, the methods of external standards, standard additions, and internal standards are gathered together in a single chapter.

A discussion of curve-fitting, including the statistical basis for linear regression with and without weighting also is included in this chapter. The design of a statistically based sampling plan and its implementation are discussed earlier, and in more detail than in other textbooks.

Topics that are covered include how to obtain a representative sample, how much sample to collect, how many samples to collect, how to minimize the overall variance for an analytical method, tools for collecting samples, and sample preservation.

Commonly used methods for separating interferents from analytes, such as distillation, masking, and solvent extraction, are gathered together in a single chapter. The six areas of analytical techniques—gravimetry, titrimetry, spectroscopy, electrochemistry, chromatography, and kinetics—receive roughly equivalent coverage, meeting the needs of instructors wishing to emphasize wet methods and those emphasizing instrumental methods.

Related methods are gathered together in a single chapter encouraging students to see the similarities between methods, rather than focusing on their differences.

Throughout the text applications from organic chemistry, inorganic chemistry, environmental chemistry, clinical chemistry, and biochemistry are used in worked examples, representative methods, and end-of-chapter problems. An important feature of this text is the presentation of representative methods. These boxed features present typical analytical procedures in a format that encourages students to think about why the procedure is designed as it is.

Two chapters provide coverage of methods used in developing a standard method of analysis, and quality assurance. The chapter on quality assurance covers quality control and internal and external techniques for quality assessment, including the use of duplicate samples, blanks, spike recoveries, and control charts. Many of the in-chapter examples and endof-chapter problems are based on data from the analytical literature, providing students with practical examples of current research in analytical chemistry.

Critical thinking is encouraged through problems in which students are asked to explain why certain steps in an analytical procedure are included, or to determine the effect of an experimental error on the results of an analysis.

Rather than including a short collection of experiments emphasizing the analysis of standard unknowns, an annotated list of representative experiments from the Journal of Chemical Education is included at the conclusion of most chapters. These experiments may serve as stand alone experiments, or as starting points for individual or group projects.

The Role of Equilibrium Chemistry in Analytical Chemistry Equilibrium chemistry often receives a significant emphasis in the introductory analytical chemistry course. While an important topic, its overemphasis can cause students to confuse analytical chemistry with equilibrium chemistry. Although attention to solving equilibrium problems is important, it is equally important for students to recognize when such calculations are impractical, or when a simpler, more qualitative approach is all that is needed.

It is important, however, to qualitatively understand that a large excess of Cl— increases the solubility of AgCl due to the formation of soluble silver-chloro complexes.

Balancing the presentation of a rigorous approach to solving equilibrium problems, this text also introduces the use of ladder diagrams as a means for providing a qualitative picture of a system at equilibrium. Students are encouraged to use the approach best suited to the problem at hand.

Computer Software Many of the topics covered in analytical chemistry benefit from the availability of appropriate computer software. In preparing this text, however, I made a conscious decision to avoid a presentation tied to a single computer platform or software package. Students and faculty are increasingly experienced in the use of computers, spreadsheets, and data analysis software; their use is, I think, best left to the personal choice of each student and instructor.

Chapters 1—3 serve as an introduction, providing an overview of analytical chemistry Chapter 1 ; a review of the basic tools of analytical chemistry, including significant figures, units, and stoichiometry Chapter 2 ; and an introduction to the terminology used by analytical chemists Chapter 3.

Familiarity with the material in these chapters is assumed throughout the remainder of the text. Chapters 4—7 cover a number of topics that are important in understanding how a particular analytical method works. Later chapters are mostly independent of the material in these chapters. The statistical analysis of data is covered in Chapter 4 at a level that is more complete than that found in other introductory analytical textbooks.

Methods for calibrating equipment, standardizing methods, and linear regression are gathered together in Chapter 5. Chapter 6 provides an introduction to equilibrium chemistry, stressing both the rigorous solution to equilibrium problems, and the use of semi-quantitative approaches, such as ladder diagrams.

The importance of collecting the right sample, and methods for separating analytes and interferents are covered in Chapter 7. Chapters 8—13 cover the major areas of analysis, including gravimetry Chapter 8 , titrimetry Chapter 9 , spectroscopy Chapter 10 , electrochemistry Chapter 11 , chromatography and electrophoresis Chapter 12 , and kinetic methods Chapter Related techniques, such as acid—base titrimetry and redox titrimetry, or potentiometry and voltammetry, are gathered together in single chapters.

Combining related techniques together encourages students to see the similarities between methods, rather than focusing on their differences.

The first technique presented in each chapter is generally that which is most commonly covered in the introductory course. Finally, the textbook concludes with two chapters discussing the design and maintenance of analytical methods, two topics of importance to analytical chemists.
