Solid salt (Nacl) does not conduct electricity but when dissolved in water, it conducts electricity.


Don't copy from internet !

​

Answer 1

Answer:

• Only Free ions can conduct electricity
• NaCl don't have free electrons, hence it can't conduct electricity
• when we dissolved NaCl in water,the ions (Na+ and Cl-) get seperated.
• Ions have free electrons moving in outermost orbit, hence, it can conduct electricity

Hence,Solid salt (Nacl) does not conduct electricity but when dissolved in water, it conducts electricity.

hope it helps :)

Answer 2

Answer:

• Sodium chloride is an Ionic compounds do not conduct electricity in solid state but they conduct electricity in aqueous solution and in molten state.Hence this property is shown by sodium chloride.
• because ions are fixed in position and cannot move but in aqueous solution and in molten state they conduct electricity as ions are free to move.
