Question
Chapter 4, Problem 4Q
Interpretation Introduction
Interpretation:
The reason for the use of smaller quantity of activated charcoal instead of its larger quantity 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

Which of the following methods is not an appropriate method for purifying a solid under normal laboratory conditions?
sublimation
Ochromatography
distillation
recrystallization
What are the uses of recrystallization, decolorization, and sublimation? Give examples of each.
2. The goal behind suction filtration is to remove soluble impurities that are on the
surface of the crystals. Therefore, why can't you simply use suction filtration
instead of recrystallization to purify an impure solid?

- Weigh out accurately 9.99 g of copper(II) sulfate pentahydrate (CuSO4·5H2O) by taring using a clean and dry empty 250-ml beaker. 2. Add tap water to the beaker to reach the 50-mL mark on the side of the beaker. 3. Dissolve all the crystals of CuSO4·5H2O in the water using a clean glass rod for stirring. 4. Then using a glass funnel transfer all the blue solution to a 100-mL volumetric flask. Rinse the beaker with about 10 mL of water and transfer the solution to the volumetric flask. Repeat the rinsing of the beaker with another 10 mL of water and transfer the solution to the volumetric flask. This is called quantitative transfer of the solution. 5. Then add enough water to reach the calibration mark of the volumetric flask. (You will need to use a dropper to add the last few drops of water to ensure the meniscus is on the calibration mark). Close the volumetric flask with a stopper and mix the solution well (so that it is homogeneous). 6.
