<p>Are there any books or websites that give a thorough review of all the recommended AP chem labs?</p>
<p>I suddenly got all worried about the ap chem labs even though I'm taking a class because I took the 2002 ap chem exam and came across two questions which required me to know the color of various aqueous solutions such as KMnO4(aq), which I had NO CLUE about and did not come across before.</p>
