Hi, my name is Rachel. I will be demonstrating the steps required for successful recrystallization. So, let's get started.
For this experiment, we're using water as our solvent, which I've already preheated. Now let's add boiling chips, followed by the impure compound. In this step, we are trying to dissolve the compound in the minimal amount of hot solvent. We'll add the hot solvent in small portions to our flask. After each addition swirl the flask and bring it to a boil before adding more. We only want to add enough hot solvent to fully dissolve our compound. Some of the impurities may not dissolve. At this point, we need to filter out the insoluble impurities from the solution while keeping the solution hot. To speed up the filtration, we fold the folder paper to increase the surface area of filtration. It is crucial to keep the entire filtration system hot to prevent premature crystallization. To do so, add a small amount of hot solvent to keep the filt
