Working With Chemistry Principles And Reactions Seventh Edition
I've used this textbook across multiple semesters of teaching general chemistry, both as a primary text and as a supplementary resource for problem sets. It sits somewhere between the heavily theoretical approach you see in upper-level books and the overly simplified treatment in some introductory courses. The Masterton and Hurley authors try to hit a middle ground, which means it has real strengths but also some glaring gaps that will trip students up if you don't know where to look. It's a standard two-semester general chemistry textbook published by Brooks/Cole CENGAGE Learning. The seventh edition came out in 2012 and covers stoichiometry, atomic structure, bonding, thermodynamics, kinetics, equilibrium, acids and bases, and introductory organic and nuclear chemistry. Nothing revolutionary in scope. The layout is clean, the worked examples are adequate, and the end-of-chapter problems range from straightforward drill to genuinely difficult applied questions in the later chapters. The main selling point for most instructors is how it handles nomenclature and equation balancing early on. Chapters three and four lay out ionic and covalent compound naming systematically, then build directly into writing and balancing equations. A lot of competitors bury that stuff or spread it across multiple chapters without tying them together clearly.
How the Problem Sets Actually Work
Here's where the book earns its keep and where it falls short, depending on who you ask. Each chapter ends with three categories of problems: Practice Exercises tied directly to the examples in the text, Follow-up Questions that connect to the chapter's core concepts, and General Problems that mix material across sections. The Practice Exercises come with answers in the back, which is useful for self-study. The issue is that the bridge between Practice Exercise answers and General Problems is wider than it should be. I noticed this consistently with students working through Chapter Eleven on equilibrium. They could nail the sample Ksp calculation in the text, then hit problem set eleven point forty-seven and stare at it for twenty minutes because the problem required combining solubility rules from Chapter Four with the common ion effect from a section that wasn't clearly flagged. The book never explicitly tells students they need to combine those two topics. You learn that by doing it enough times or by paying attention in lecture. My workaround for that specific gap was to create my own cross-reference sheet. I'd list each chapter's major topic areas and note which later chapters depended on them. It took about an hour to prepare before the semester, but it saved me from fielding the same confused office hour questions all quarter. Students who had that map from day one tended to self-correct faster when they hit a problem that pulled from multiple chapters.
Where the Textbook Has Real Blind Spots
The quantum mechanics section in Chapter Eight is competent but thin. It introduces wave-particle duality, the uncertainty principle, and the Schrödinger equation results without much mathematical derivation. For a class aimed at biology and health sciences majors, that's probably appropriate. For a class feeding into physical chemistry, students will need supplemental material. I've had several students tell me they couldn't follow senior-level courses afterward because the book never walked through how the quantum numbers actually connect to electron configuration rules in any deep way. It states the Aufbau principle, it states Hund's rule, but the underlying "why" gets a paragraph or two at most. The thermodynamics coverage in Chapter Six has a similar issue but in the opposite direction. It goes deep into enthalpy and entropy calculations but barely touches Gibbs free energy beyond the basic equation delta G equals delta H minus T delta S. The connection between free energy and equilibrium constants appears late in the chapter and isn't developed with enough practice problems. I found students consistently weak on predicting whether a reaction is spontaneous at different temperatures because the book never gave them structured practice with temperature as a variable.

A Note on the Answer Key and Solutions Manual
The back-of-book answers give numerical results but skip significant steps. If you're working through a multi-step stoichiometry problem and your answer doesn't match, you won't easily find where you went wrong by looking at the provided solution. The official Student Solutions Manual, which is sold separately, walks through about a third of the odd-numbered problems in detail. That leaves roughly two-thirds of the practice problems with minimal guidance. I always recommend students pair the textbook with an online resource like Khan Academy or Paul's Online Math Notes for the problems the manual doesn't cover. The book isn't designed to be a standalone learning system, even though some students treat it that way. Chapter Fifteen on acids and bases is where I see the most confusion. The treatment of polyprotic acids is adequate but the Ka1 versus Ka2 versus Ka3 simplification—that you only need to consider the first dissociation for pH calculations—is presented in a way that makes it seem like an arbitrary rule rather than a justified approximation. Students who memorize the rule without understanding why it works get blindsided by problems that ask for the concentration of the fully deprotonated species. The book mentions this in passing but doesn't reinforce the reasoning. The electrochemistry chapter is generally strong, though. Cell potential calculations, the Nernst equation, and the relationship between delta G and E cell are all covered with reasonable clarity. The connection to industry applications like battery chemistry and corrosion prevention adds context that some competing texts skip entirely.
Who Should Actually Use This Book
This works well for a standard two-semester sequence at a community college or a research university where the pace is moderate. It's not aggressive enough for a honors AP-style first semester where students need more mathematical rigor upfront. It's also not light enough for a remedial developmental chemistry course where students need more scaffolding and fewer assumed prerequisites. If you're self-studying, plan to supplement. The book is a solid reference but it assumes you have a instructor or a study group to point out the connections between topics that the text itself leaves implicit. The 2012 edition doesn't have the kind of companion digital platform that newer editions of competing textbooks include, so you're working with what's on the page. That's not necessarily a bad thing. Some people prefer it that way. But it does mean the learning experience depends more on how actively you engage with the material rather than the book carrying you through it.
