theoretically....what material is suppose to have the highest purity, the distillate (which are the first vapors to produce ) or the pot (which is the last of the vapors )? explain why one would be higher than the other? I'm confused as to the theory of this lab and need to know exactly why...Thanks! I have this lab next week and can't unnderstand what the concept is.
