alleryWater vapour is absorbed by anhydrous calcium chloride but:
AFrozen by gel
BAdsorbed by gel
CRepelled by gel
DIgnored by gel
Answer & Solution
Correct answer: B. Adsorbed by gel
1. The calcium chloride takes the water right into its bulk.
2. Silica gel holds it at the surface only.
3. So the same vapour is absorbed by one and adsorbed by the other.
