Most professors assume you forgot everything over the summer anyway, if you want to be really prepared re-study the chapters on molecular bonding theories and make sure the basics like mole conversions and balancing equations are still second nature, on my first orgo test I got the entire first page wrong because I forgot how to do simple mole conversions. Most of the stuff, however, is new. If you did well in gen chem, then you will relearn the repeated stuff really fast.

I am looking for a list of relatively easy distillations from common chemicals. By "realtively easy" I mean distillations that can be performed with a basic distillation setup + a vigreux column and by "common chemicals" I mean chemicals that I can buy from supermarkets, hardware stores, pool chemicals, etc... By "useful" I mean ideally I would like to be able to use the finished product in some way, for example distilling acetic acid from white vinegar and using it in aspirin synthesis. I just got all the glassware but all I've distilled so far is salt water! My chemistry experience consists of two semesters of inorganic chemistry and two semesters of organic chemistry, I have about 150 hours of lab experience.
