Question

Anode and cathode connected to a bulb were dipped in three different containers. Container one contains solid magnesium chloride, container two contains molten sodium chloride and container three contains aqueous solution of aluminium chloride. In which of the three setups will the bulb glow? a. All three containers. b. Only container one and two. c. Only container one and three. d. Only container two and three.

Answer 1

Answer:

Only container 2 and 3 will conduct electricity because solid magnesium chloride's ions are tightly packed making it impervious to conduct electricity, whereas molten salt and aqacious ammonium chloride can conduct electricity.

hope this helps
