oxidation reaction

Question 16

Why does the electrolyte have to be aqueous or molten?

Answer 16

because solid compounds cannot conduct electricity, the ions are locked in place and are NOT free to move&raquo_space; strong electrostatic forces between particles&raquo_space; these are broken when aqueous or molten
