Q: When water and chloroform, CHCl3, are mixed, the two components separate into two distinct layers, each of which smells strongly of chloroform. Account for these observations in terms fo the polarity of the two substances involved. Describe how you could very quickly determine which of the two layers is mainly water and which is mainly chloroform. H2O is a polar molecule. CHCl3 is also a polar molecule. Given that "like dissolves like" they should turn into one solution.
