Use 5th edition if you can...

Customer Rating:

There is very little difference between this edition and the previous one which is normally the case with college textbooks today. It's a mystery to me why colleges use any material by this author. Brooks and Cole should stop publishing him. The Zumdahl methods for teaching chemistry are truly awful. You can find various mistakes in this and previous editions of this text. His derivation regarding the ideal gas law is one example. Why even include it in the text if you can't do it correctly? He obviously does not understand basic Newtonian Physics.

Chemical Principles	Customer Rating:
Chemical Principles Chemical Principles is a fantastic book! I use it as a reference text with anything i dont understand being looked up straight away in this book. I am a high school student who has found this book to be very useful in my studies of chemistry! I recommend that you buy this book as i found it easy to understand and has many examples questions and activities for you to do.

Waste of Money

Customer Rating:

Not only did my chemistry class not use this book, but I cannot imagine how ANY class could use this. This book is so badly written, that it isn't even worth opening. It doesn't follow any particular order, and it frequently jumps back and forth between highly advanced topics and surprisingly dumb examples. Reading through even a single chapter of this book will lower the intelligence quotient of any sane individual. I suppose this book could serve a useful purpose, but only if that purpose was to teach the students to forget what they already knew about chemistry. I think I've made my point: do not buy this book under any circumstances.

Why does my university use this book?

Customer Rating:

Why does my university use this book? The University of Washington uses this book to weed out the pre med students. Why do they choose this book? Zumdahl purposely wrote this book to be confusing. Try reading pp. 668 through 670 in the fifth edition. He wrote this to be especially confusing by not being consistent with phase signs nor giving clear statements, such as "When the phase of the right orbital is reversed and combined with the left orbital." What orbitals is he talking about? The ones on a figure, that happen to be on a different page, which is not in view when reading this page? This book is horrible and is designed for the student to fail. Thank you Zumdahl and UW for trying to ruin chemistry for your students.
