Sodium chloride has a crystalline structure made up of Na+and Cl−ions. Why does NaCl not conduct electricity in solid state?
A
Solids do not conduct electricity.
B
The ions of NaCl become mobile only in molten state and are not free to move in solid state.
C
The crystalline structure does not have ions.
D
When a bond is formed between ions they lose their charge.
Answer
The ions of NaCl become mobile only in molten state and are not free to move in solid state.
Explanation
Solution
: Due to electrostatic force of attraction, the ions do not move when electric current is applied in solid state The ions become mobile when melted or dissolved in a polar solvent and conduct electricity.
