Ethanol Distillation Post-Analysis
answer the following questions about the Ethanol Distillation lab.
- What is an azeotrope? What is the boiling point and composition of the azeotrope used in this lab?
- Is this ethanol-water azeotrope a pure liquid? (think about its constant boiling point)
- Which fractions of the fractional distillation contain the greatest percentage of ethanol? What is the major component of later, higher boiling fractions?
- What specific type of azeotrope is the ethanol-water mixture used in this lab? Explain who this mixture represents a minimum-boiling azeotrope.
- Compare and contrast the observed differences between simple distillation and the fractional distillation for separating the ethanol-water mixture used in this lab.
