- Which of the following statements is true when considering temperature during a recrystallization? More than one answer may be correct. Using ice to cool the sample will speed up the crystallization process so that large crystals will be formed. It is important that the sample is dissolved in just enough hot solvent. O Ideally the hot solvent used will keep the impurities dissolved OR not dissolve them at all. Enough cold solvent should be added to dissolve the sample BEFORE heating it past its boiling point.Why is recrystallization not applicable to samples which contain large amount of impurities?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.
- 2. When performing the recrystallization of an impure solid, why is it advised to use the minimal amount of solvent possible? Group of answer choices To minimize the amount of pure solid lost due to its solubility. To minimize the cost of the recrystallization. To reduce the time needed to filter the pure solid from the solvent after recrystallization. To minimize the amount of hazardous materials used.An ideal recrystallization solvent should have a large gradient of solubility along with temperature, has the ability to dissolves the impurities very well and must not chemically react with the product. For each of the three reasons given, give an explanation for why they are a reason that make an ideal recrystallization solvent?A 1.59 g sample containing KI was analyzed gravimetrically and 0.0538g of Barium Iodate was recovered... express the results of this analysis as percent posassium iodide.

Describe a method to separate salt from a homogeneous mixture of salt water so that it is in the form of a solid at the end of the separation process.An ideal property of a solvent to be suitable for recrystallization of a solid sample is: Group of answer choices To have a high boiling point. To dissolve the solid at room temperature but not in cold temperature. To react with the solid to be recrystallized. To dissolve the solid at the solvent's boiling temperature but not at room or cold temperature.
