Dear All,
   
  This goes out to those expert in fractional distillation : A mixture contains 2 organic liquids (completely miscible with each other), one with a boiling point of 80 deg C and the other with a boiling point of 35 deg C.
  Can the two liquids be completely seperated by fractional distillation using a very long column or will they behave as a binary azeotropic mixture at constant pressure (constant boiling point mixture) and the distillate still contain proportions of both mixtures ?
  I'am asking as I have not fully understood the concept; some say the mixtures are not seperable while others say the mixtures are completely seperable; am confused.
