Which consequence results when anhydrous calcium chloride is exposed to humid air?

A)Deliquescence occurs, forming a solution
B)Sublimation occurs, forming vapor
C)Efflorescence occurs, forming powder
D)Desiccation occurs, remaining solid

💡 Explanation

Deliquescence occurs because calcium chloride is ionic and vigorously attracts water molecules from the air, leading to the formation of a saturated solution through dissolution, therefore deliquescence happens rather than efflorescence, which would expel water at a higher moisture content.
