A ternary mixture of water n-butanol HMF is described by the following ternary phase diagram see below. 

a) Of the three possible binary pairs (water butanol, butanol HMF, and water HMF) which are completely miscible and which exhibit LLE? 

b) What is the composition at the plait point for this ternary mixture? 

c) For mixture containing 5 kg of water, 2 kg of HMF (hydroxymethylfurfural) and 5 kg of butanol, how many phases will be present, what will be their compositions, and how many total kg will be in each phase?
