- List and describe two methods that can used to improve the separation of a liquid mixture by fractional distillationCompare simple and fractional distillation for the separation of HEXANE and TOLUENEWhy is the Refractive Index of hexane closer to the refractive index of heptane in both simple and fractional distillation?
- What are the differences between a simple distillation and steam distillation?Why is fractional distillation more efficient than simple distillation when purifying liquid mixtures?A sample contains a mixture of t-butanol and n-butanol. What type of distillation, simple or fractional, would be best employed to separate the two liquids? Why?
- in fractional distillation, how do you tell which liquid is in which fraction and which fraction has a mix of liquids if you are trying to seperate cyclohexane and toluene?? what would the density and boiling point of the first fraction beCompare the simple distillation of pure hexane and binary mixture of hexane and toluene to that of a fractional distillation?Students were tasked to conduct a recrystallization experiment to test the ability of the newly discovered solvents in their laboratory to purify and separate a mixture containing compounds X and Y. The solubility of the two compounds in g/50 mL of hot and cold solvents are given by the photo.
- You were given a mixture of two miscible solvent A and B that you are tasked to separate. You know that solvent A has a boiling point of 49 oC while solvent B has a boiling point of 174 oC. Which of the listed method would overall be the most efficient? Fractional distillation Recrystallization Solid-liquid extraction Liquid-liquid extraction Simple distillation Acid-Base extractionHow the concept of vapor pressures would differ between simple distillation and steam distillation and how this applies to the latter. Taking the extraction of essential oils as an example, why would the use of chlorinated organic solvents such as dichloromethane be useful their extraction over other organic solvents?6.0 mL of cyclohexanol, 8 mL of 85% phosphoric acid, and 10 drops of sulfuric acid are added to a 50-mL round-bottom flask with boiling chips, and the mixture is distilled into an ice-cooled receiver. The distillate is in the form of a colorless bi-phasic mixture. The cyclohexene upper layer is removed from the water layer, and dried over anhydrous calcium chloride. Isolated is cyclohexene as a clear and colorless foul-smelling liquid. Weighing data is given below. Gross mass: 51.24 g Tare mass: 48.04 g Product mass: 3.2g Question: Calculate the theoretical mass of the cyclohexene product, bearing in mind that the cyclohexanol starting material was measured by volume, not by mass (so you must use the density of cyclohexanol to convert milliliters to grams, before calculating the number of moles). Calculate the percent yield of cyclohexene obtained.
