During electrolysis of water,the volume of $O_2$ liberated is $2.24 \ dm^3$. The volume of hydrogen liberated,under same conditions,will be .............. $dm^3$.

What is produced at the cathode during the electrolysis of aqueous $Na_2SO_4$?

During the electrolysis of molten $NaCl$, some water was added. What will happen?

Which of the following is $NOT$ true about the electrolysis of molten $NaCl$?

The main reason for not using a mercury electrolytic cell in $NaOH$ manufacture is that

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?
