Describe the characteristics of a good recrystallization solvent The solubility of a compound is 59 g per 100 mL in boiling methanol and 30 g per 100 mL in cold methanol, whereas its solubility in water is 7.2 g per 100 mL at 95 degree C and 0.22 g per 100 mL at 2 degree C. Which solvent would be better for recrystallization? Explain why. In what circumstances is it necessary to...
why is p ether not a good solvent for recrystallization of acetanilide

9. During the recrystallization of the benzil, an extra 7 ml of the recrystallization solvent is added after the minimum amount is found. This extra is added because the benzil crystals are light and fluffy and adsorb most of the solvent if the extra solvent is not added. Why would it be detrimental to not have any solvent left after the crystals have formed during recrystallization.
what are the properties of an ideal recrystallization solvent?
Synthesis of aspirin Describe the process of recrystallization: The sample solute is just dissolved in a ___________ solvent. The sample is then allowed to _______________ before placing it in a(n) ______________ allowing ____________ to form. During recrystallization, the ______________ stay dissolved in the solution while the _________________ is recovered during filtration.

What are the advantages of using a solvent pair for
recrystallization? Select all that apply.
What are the advantages of using a solvent pair for recrystallization? Select all that apply. You can quickly make the solution supersaturated by adding more of the solvent with greater dissolving power. You can calculate the precise amounts of the solvents needed for recrystallization. You can quickly make the solution supersaturated by adding more of the solvent with less dissolving power. You don't have to...
