AP: Descriptive Chem Practice
To help us reach that perfect 15 out of 15 (in three minutes or less) on "Question 4" of the AP Chem exam, this excellent "teaching" site will give you countless practice problems.

Just create a free account and then you can practice at will and you can get instant feedback.
The good thing about descriptive chemistry is that, once it "clicks" and you can "see" the products that will form from any of the eight common chem. reaction types, you and others will think that you have magical powers as you spout off sound bites such as, "...(chortle) of course, double replacement with precipitation...solid magnesium phosphate forms from those reactants" or "...child's play, an obvious metal-ligand complex reaction forming hexaammine copper II ion complex; note the number of ligands is twice the transition metal's charge...tee-hee!" or "Why are you walking away from me? I can't quit you!"
