What would be the best method in separating the following mixtures and why?
Recrystallization, Solvent Partitioning, Fractional Distillation, Column Chromatography, or Thin Layer Chromatography
A) urea and trans-cinnamic acid
B) cyclohexane and benzene
C) cyclohexanone and urea
D) cyclohexene and ethylacetate
Homework Answers
A) urea and trans cinnamic acid have similar boiling point and both are water soluble.
Thus, can be separated by recrystallization
B) Cyclohexane and benzene are separated by fractional distillation method because the melting point of these two liquids are close to one another. Thus, can't be separated by simple distillation thus fractional distillation is the useful technique for the separation of both.
C) cyclohexanone and urea are separated by solvent partitioning due to large Difference in the solubility.
D) Cyclohexene and ethyl acetate are separated by column chromatography because of difference in affinity towards the stationary and mobile phase.

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
