← ScienceWhich mechanism limits the growth of macroscopic crystals from molten sodium chloride?
A)Charge repulsion inhibits ion aggregation✓
B)Hydrogen bonding limits crystal volume
C)Covalent bond saturation ends growth
D)Van der Waals forces equalize surface tension
💡 Explanation
Charge repulsion inhibits ion aggregation because NaCl forms ionic bonds, resulting in alternating positive and negative ions. Therefore, continued ion addition encounters increased electrostatic repulsion rather than continued crystal growth because of more favorable energetics.
