The caking of crystals can be prevented by _____________________?
Correct answer: B. Both A. and C.
- A. Maintaining high critical humidity
- B. Both A. and C.
- C. Coating the product with inert material
- D. Maintaining low critical humidity
Explanation
Caking is reduced by keeping the product environment below the critical humidity and by coating crystals with an inert material. A high critical humidity is also desirable because the product then resists moisture uptake under ordinary conditions, so both listed preventive measures are intended in this convention.
