Which process dictates sodium chloride's high melting point due to its ionic structure?

💡 Explanation

When heated, NaCl requires overcoming powerful electrostatic forces between Na+ and Cl- ions, defined by Coulomb's Law, resulting in stability and high melting point. Therefore high temperatures are needed to break apart the ionic lattice, rather than weaker intermolecular forces, directional covalent bonds, or surface interactions.
