← ScienceWhich outcome occurs when subjecting NaCl crystals to high humidity?
A)Hygroscopic deliquescence causes surface dissolution✓
B)Increased ionic conductivity strengthens bonds
C)Covalent character increases crystal rigidity
D)Crystal lattice rearranges forming allotropes
💡 Explanation
Hygroscopic materials like NaCl absorb moisture; therefore, high humidity causes immediate surface dissolution via deliquescence because the ionic bonds weaken at the crystal surface rather than other bond strengthening.
