How to fill out experiment 8 recrystallization?

1. Gather the necessary materials and equipment. This may include a solid compound, a suitable solvent, heating equipment, glassware, and filtration equipment.
2. Begin by weighing the solid compound that you will be recrystallizing. Use an analytical balance to obtain an accurate measurement.
3. Next, choose a suitable solvent for recrystallization. Consider the solubility of the compound in various solvents and select one that will dissolve the compound at elevated temperatures but not at room temperature.
4. Dissolve the solid compound in the chosen solvent by adding the solvent to a clean, dry beaker and heating it until boiling. Slowly add the compound to the boiling solvent while stirring until it dissolves completely.
5. After all of the solid has dissolved, remove the beaker from heat and set it aside to cool. As the solution cools, crystals will start to form. You can speed up the process by using an ice bath or placing the beaker in a refrigerator.
6. Once the solution has cooled, filter the crystals from the mother liquor. Use a Buchner funnel or a Hirsch funnel with filter paper to separate the crystals from the liquid. Apply gentle suction to speed up the filtration process.
7. Wash the filtered crystals with a small amount of cold solvent to remove any impurities or residual mother liquor. Drain the liquid off the crystals and repeat the washing process if necessary.
8. Finally, collect the purified crystals onto a watch glass or a pre-weighed filter paper. Allow the crystals to air dry until no more solvent is present. Weigh the dried crystals to determine the yield of the recrystallization.
