- If a mixture is distilled rapidly, the separation of its compound is poorer than if the mixture is distilled slowly. Please explain why is that so using your own understanding. I don't need a copy-pasted answer from google.List and describe two methods that can used to improve the separation of a liquid mixture by fractional distillationWhy do two layers form when solutions containing water are added to the extracted dichloromethane (CH2CI-2) solution?
- 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 extraction3. Describe the characteristics that a crystal obtained through recrystallization must have, the final crystal, not the solvent.The followings methods are useful to induce crystallization EXCEPT adding a small crystal of the desired compound, called a seed crystal, to the solution adding anhydrous potassium carbonate to the solution and cooling it in an ice bath scratching the inner wall of the Erlenmeyer flask with a glass stirring rod reheating the solution to boiling to boil off some of the solvent, and then allow the solution to cool to room temperature again to effect crystallization
- A student performs a crystallization on an impure sample of biphenyl. The sample weighs 0.5 g and contains about 5% impurity. Based on his knowledge of solubility, the student decides to use benzene as the solvent. After crystallization, the crystals are dried and the nal weight is found to be 0.02 g. Assume that all steps in the crystallization are performed correctly, there are no spills, and the student lost very little solid on any glassware or in any of the transfers.
