When performing a recrystallization of an impure solid, why is it important to allow the heated solution to cool slowly? Group of answer choices To encourage greater solid solubility. For the molecules of the solid being purified to arrange in organized crystal lattices. To avoid the need for using ice to cool the solution. To trap particles in the crystal lattice.
Why would industry prefer to purify solids by sublimation or zone refining rather than recrystallization? (Hint: is there anything wasteful about recrystallization)
1. What limitations are encountered in the application of sublimation as a general method of purification? 2.Explain how a process of fractional sublimation might be applied to a mixture of two substances which sublime closely together.
Briefly explain how slow cooling contributes to the formation of pure crystals during recrystallization.
What limitations are encountered in the apolication of sublimation as a general method of purification?
You've just synthesized a new molecule and need to purify it by recrystallization. You find that it is poorly soluble in water and highly soluble in ethanol, even when cooled in ice. What solvent should work in this situation? a. water b. Recrystallization from any solvent is impossible. c. methanol d. a solvent mixture - water and ethanol
TRUE OR FALSE: 1. Solids such as naphthalene when heated will pass thru a process called condensation prior to sublimation when being purified. 2.If water and n-propyl alcohol were mixed, the separation of individual components is possible with steam distillation because these two have a wide range of boiling point difference. 3. When an impurity in the synthesized camphor such as sodium chloride is present, the sublimation technique cannot be used to purify the camphor due to the nature of NaCl. 4. Organic solvents such as hexane or ether are an excellent medium to recrystallize an impure benzoic acid 5. In caffeine extraction, it is important that the tannic acid component of coffee be converted to its free acid state to avoid any interference with the extraction of caffeine
Give clear handwritten solution- What is the normal boiling point of this compound? (Using phase diagram given)
Impure acetanilide was dissolved in hot water. The solution was filtered hot and the beaker of solution was immediately placed in an ice-water bath instead being allowed to cool slowly. What will be the result of cooling the solution in this manner?
How can solid solution occur between materials?
If acetone is miscible with both water and xylene, then why can’t all three form a clear single phase mixture?
SHOW COMPLETE SOLUTION AND WRITE LEGIBLY The normal boiling point of hexane is 69.0 °C. Estimate (i) its enthalpy of vaporization and (ii) its vapor pressure at 25 °C and at 60 °C. (Hint: Trouton’s rule).
