During the process of crystallization, the hot saturated solution:
Correct answer: B. Is cooled at a moderated rate to get medium-sized crystals
- A. Is cooled very slowly to get large-size pores in it
- B. Is cooled at a moderated rate to get medium-sized crystals
- C. Is evaporated to get the crystals of the product
- D. Is mixed with an immiscible liquid to get the pure crystals of the product
Explanation
The hot filtered solution is cooled at a moderate rate so that medium sized crystals are formed. Slow cooling yields bigger crystals which are likely to include considerable amount of solvent carrying impurities with it and complicating the drying process.
