Select the correct statements regarding electric conduction.
Happens by the movement of ions
Involves the transfer of matter.
Electric conduction happens by the movement of ions, hence it involves the transfer of matter (ions in this case).
Example: Electrolysis of lead bromide
PbBr2⇌ Pb2++2Br−
Lead ions move towards cathode (-ve electrode) and Bromide ions move towards (+ electrode) anode leading to electric conduction.
