a.      Discuss which technique,simple distillation or fractional distillation, shall be the mostefficient on purifying the mixture of solvents? Elaborate   (4 points)
b.     Which solvent should bedistillated first, cyclohexane or Toluene? Elaborate.(3 point)
c.     How the RI measurements support(or not?) your expectations in the item b? (2.5 points)
d.     Making use of the RImeasurements, explain if your distillation was successful. (3points)
RI values:
Fraction | Observed Refractive Index (n20D) | Corrected Refractive Index (n20D) |
Fraction 1 | 1.3975 | 1.3989 |
Fraction 2 | 1.4260 | 1.4274 |
Fraction 3 | 1.4865 | 1.4879 |
e.      Would re-distillation ofindividual fractions improve the purification of individualsolvents? Elaborate.                                                     (2.5 points)
