← ScienceWhich consequence results when high humidity contacts hygroscopic ionic salts?
A)Deliquescence causes lowered surface resistance✓
B)Efflorescence causes increased crystal hardening
C)Hydrolysis forms insoluble metal hydroxides
D)Sublimation results in material strength
💡 Explanation
Deliquescence occurs because water molecules are attracted by strong ionic interactions, exceeding lattice energy; therefore, water absorption lowers resistance rather than crystal hardening, which is efflorescence, under differing conditions.
