Question
Chapter 4, Problem 3Q
Interpretation Introduction
Interpretation:
The circumstances required for the use of activated carbon during recrystallization should be determined.
Concept introduction:
Recrystallization is a technique that is used to purify the impure compounds. It is based on the principle that the solubility of substances increases with the increase in temperature.
Following are some of the types of recrystallization:
- Single-solvent recrystallization
- Multi-solvent recrystallization
- Hot filtration-recrystallization

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.arrow_forwardWhich 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.arrow_forward
- What are the differences between a simple distillation and steam distillation?arrow_forwardYou are attempting to purify a compound via recrystallization. You prepare the process through the following method: 1) Dissolve the material in a minimal amount of hot EtOH. 2) Slowly add hot water until the compound is slightly cloudy. 3) Add a small amount of EtOH until the solution is just clear (still hot). 4) Cool to RT. Upon cooling to RT you notice that the compound is not precipitating out of solution. You decide to boil off some ethanol. Upon completing this step and cooling to RT you notice that the compound is precipitating out as desired! In which solvent is your compound the least soluble? Ethanol O Water O The ethanol water mixture Insoluble in all of these solventsarrow_forwardExplain the principle behind vacuum distillation.arrow_forward
