Suppose you are performing an experiment in which you are insructed to mix 10 g of a unknown solid 50 mL of unknown liquid. Upon mixing the two substances you find that thhe solid disappears. If you are to presume this change was merely physical in nature. How would you go about seperating the two components to recover as much of starting materials as possible?
