3.briefly state the basic steps in the recrystallization of a solid sample. The key features of this technique is causing a solid to go into solution, and then gradually. Because of the compound which is trying to purify recrystallizes. If the substance is dissolved in a solvent, then use crystallisation. Cool the solution to crystallize. Apply heat to dissolve the solid. What problems might arise if a hot solution is filtered byvaccum. If insoluble impurities are present, you should perform a hot filtration. If the substance is a solid mixed in a solvent, begin by filtering (or decanting). Add a small quantity of appropriate solvent to an impure solid.
When doing a recrystallization, what observations wouldprompt you to perform a hot filtration? To purify of a compund sufficient amount of solvent is required not to use too much solvent. Web evaporation requires heat (or air movement above the sample) to drive off a volatile solvent. What problems might arise if a hot solution is filtered by vaccum. If the substance is dissolved in a solvent, then use crystallisation. Because of the compound which is trying to purify recrystallizes. Use a separate bullet point for each step. The key features of this technique is causing a solid to go into solution, and then gradually. Web when doing recrystallization, what observations would prompt you to perform a hot filtration? It is a technique used for. When doing a recrystallization, what observations would prompt you to perform a hot filtration?2.
