Ou are subliming camphor and you note that pure camphor is condensing nicely on the cold finger. You check on the process several minutes later and you see that the amount of camphor on the cold finger has not changed appreciably since the last time you looked at it. However, there is still plenty of impure camphor left at the bottom of the flask. What do you suppose is the reason and what do you need to do.
