← ScienceWhich reaction occurs when sodium chloride dissolves in water?
A)Increased ion solvation stabilizes separated ions.✓
B)Covalent bond formation with water increases.
C)Lattice energy directly overcomes disorder.
D)Hydrogen bonding prevents effective attraction.
💡 Explanation
Ion solvation causes dissolution because water molecules surround and stabilize separated Na+ and Cl- ions via ion-dipole interactions; therefore, solvation predominates, rather than the ions remaining bound within rigid crystal lattice.
