Which technique (simple, fractional, or steam distillation) should be used to separate a hexane-water mixture.
Which technique (simple, fractional, or steam distillation) should be used to separate a hexane-water mixture.
Homework Answers
Steam distillation is used to separate hexane-water mixture.Because hexane does not dissolve in water. So, for two immisible liquid we use steam distillation

A simple distillation was performed to separate a mixture containing both hexane and heptane. Explain why the observed starting vapor temperature in the simple distillation should be above the boiling point of hexane. Then, explain why if a fractional distillation was performed instead you would have a better separation (be sure to include how the fractionating column works in your explanation).

What are the applications of simple and fractional distillation A)Simple distillation is used when a substance is less than 10% impure while fractional distillation is used to purify a compound when the impurities are greater than 10% of the mixture. B) Simple distillation is preferred when a higher percent recovery of pure material is desired. C) Fractional distillation is preferred when a higher percent recovery of pure material is desired. D) Simple distillation must be done if the compound has...
