Which of the following does not conduct electricity?
- A Fused \(\mathrm{NaCl}\)
- B Solid \(\mathrm{NaCl}\)
- C Brine solution
- D Copper
Answer & Solution
Correct Answer
(B) Solid \(\mathrm{NaCl}\)
Step-by-step Solution
Detailed explanation
Solid \(\mathrm{NaCl}\) does not conduct electricity because the ions \(\left(\mathrm{Na}^{+}\right.\)and \(\left.\mathrm{Cl}^{-}\right)\)are well arranged in the crystal structure and not free to move to conduct electricity.
