1 Answer

Answer :

(3) Salt water Explanation: Pure water is actually an extremely poor conductor, but saturated salt water is a good conductor. The saltier the water, the better the conductance. The reason it conducts electricity is because the NaCl (sodium chloride) breaks apart into a positively charged Na+ and a negatively charged Chlorine CF. When current is applied, it is easily conducted by the highly charged ions.
