Which of the following statements is correct regarding the electrolysis of molten $NaCl$?

An aqueous solution of $CuSO_{4}$ is subjected to electrolysis using inert electrodes. The $pH$ of the solution will

Electrolytes can conduct electricity because

How many electrons flow through the wire if a current of $1.5 \ A$ flows through it for $3 \ hours$?

Which of the following is produced by the electrolysis of molten $NaCl$?

An aqueous solution containing $1 \ M$ each of $Cu(NO_3)_2$,$AgNO_3$,$Hg_2(NO_3)_2$,and $Mg(NO_3)_2$ is electrolyzed using inert electrodes. Given the standard reduction potentials: $E^{\circ}_{Ag^+/Ag} = 0.80 \ V$,$E^{\circ}_{Hg_2^{2+}/2Hg} = 0.79 \ V$,$E^{\circ}_{Cu^{2+}/Cu} = 0.34 \ V$,and $E^{\circ}_{Mg^{2+}/Mg} = -2.37 \ V$. What is the correct order of deposition of metals at the cathode?
