EXACTLY the same as 4th edition
I have a copy of the fourth edition of this text and a copy of the "updated" fourth edition. So far, I've found each randomly chosen page to not only be the same text, but same pictures and same format. The problems that I've looked at randomly throughout the book are the same in both copies, so I would believe that all of them are the same. There are some minor differences, such as the "Chemistry NOW" sidebar information that may or may not be important to your studies. The cover is also a different color, and the periodic table is now across the front cover and the first page and is embossed, so that you know it's been updated.
