Pure water is a poor conductor of electricity but aqueous solution of sodium chloride conducts electricity.

Question

Give scientific reason:

Pure water is a poor conductor of electricity but aqueous solution of sodium chloride conducts electricity.

Answer 1

• Pure water does not contain any free ions. 
• Sodium chloride (NaCl) is an ionic compound made up of sodium cation (Na⁺) and chloride anion (Cl)
• When sodium chloride is dissolved in water , these ions dissociates in its aqueous solution. ‘
• These ions are free to move in the solution and conduct electricity.
• Therefore, pure water is a poor conductor of electricity but aqueous solution of sodium Chloride conducts electricity.
