Question

Why cant (NaCl) light the bulb until the NaCl is dissolved in water. *

Answer 1

Answer:

NaCl will only conduct electricity in solutions

Explanation:

For electrical conduction, free mobile electrons as seen in most metals must be present or ions which are charged particles must be available for solutions and molten substances.

• Sodium chloride is an ionic compound without free mobile electrons or ions despite being ionic.
• It will maintain a subtle and unique charge stability when in solid form.
• In solid, the ions are not free to move and remain locked up in the solid mass.
• When introduced into a solution, the ions becomes free to move and this will aid electrical conduction.
