Which outcome occurs when hygroscopic ionic salts deliquesce?

A)Surface conductivity increases significantly
B)Crystalline structure becomes more stable
C)Internal temperature drops drastically
D)Vapor pressure above decreases

💡 Explanation

Surface conductivity rises because deliquescence causes ions to dissolve in adsorbed water, creating an electrolytic surface layer due to ionic dissociation; therefore conductivity increases, rather than being stable or decreasing pressure which would happen under different solvation conditions.
