Question

Common salt in solid form acts as

• A. Insulator
• B. Conductor
• C. Electrolyte
• D. None of these

Answer 1

The correct option is A

Insulator

Correct option is A: Insulator

1. There are ions in solid sodium chloride, but they are trapped in the ionic lattice and cannot migrate.
2. Solid ions or compounds, such as NaCl (common salt), do not carry electricity.
3. It must first be melted, molten, or dissolved in a solution (such as water). The electrons will only be free to go to either the Cathode (-ve) or the Anode (+ve) after that.
4. The electrons are free to flow in a liquid state.

Hence option A is correct
