I forgot who, but somebody had wanted the ISBN of the chem 102 books since th bookstore is all greedy and doesn't give them away. Anyway, according to the bookstore site they're still using oxtoby and the latest edition is the 4th acording to the brooks/cole. It's ISBN is 0030331889. The solutions manual ISBN is 0030332389 and the study guide ISBN is 003033231. Note that are other things you'll probably have to buy, an OWL access code for sure.
Also, please don't consider this set in stone. It's most likely they're still using the 4th edition and the chance of 5th edition showing up in three days and everybody having kept it a secret until now it is very slim.
