Which of the following does not conduct electricity?
1 Fused NaCl
2 Solid NaCl
3 Brine solution
4 Copper
Explanation:
Solid NaCl does not conduct electricity due to absence of free ions.

Which of the following will form the cathode with respect to iron anode in an electrolyte cell?
1 \(\mathrm{Mg}\)
2 \(\mathrm{Al}\)
3 \(\mathrm{Cu}\)
4 \(\mathrm{Zn}\)
Explanation:
In electrolytic cell the cathode is of higher reduction potential.Out of the given metals, Mg has higher reduction potential , hence, act as cathode. So, the correct option is (1).

On passing electric current through an electrolyte solution, the cations generally
1 Move towards cathode with the speed equal to that of anions towards anode
2 Move with faster speed than that of anions
3 Move with different speed as compared to that of anions
4 Move with slower speed than that of anions
Explanation:
Generally, the cations move with different speed as compared to that of anions.
