← ScienceWhich consequence results when industrial-grade sodium chloride absorbs humid air?
A)Surface deliquescence induces a brine film✓
B)Crystalline structure maintains rigidity indefinitely
C)Sodium chloride forms a supersaturated solution
D)The electrostatic forces ensure water repulsion
💡 Explanation
Surface deliquescence occurs because water molecules interact strongly with sodium and chloride ions. The hygroscopic nature enables the dissolution of the salt via ionic attraction, therefore a brine film forms, rather than rigidity or direct water repulsion.
