Which of the following statements is/are correct? — Electrochemistry Chemistry Question

💡 Solution & Explanation

Molten NaCl is an ionic liquid where free-moving Na^+ and Cl^– ions conduct electricity. Solid NaCl has ions fixed tightly in a crystal lattice and behaves as an insulator. Molten elemental sodium is a metal and conducts electricity excellently due to its sea of mobile, delocalized electrons. Resistivity is the reciprocal of specific conductivity (κ), not molar conductivity. Therefore, correct answer is A,C.
