If $1 \ A$ of current is passed through $CuSO_4$ solution for $10 \ s$,then the number of copper ions deposited at the cathode will be about

When $CuSO_4$ is electrolyzed using platinum electrodes,what happens?

Which among the following is correct for the electrolysis of brine solution?

During the electrolysis of copper sulphate aqueous solution using copper electrodes,the reaction taking place at the cathode is:

Which of the following chemical reactions occurs at the anode during the electrolysis of a highly concentrated $H_2SO_4$ solution?

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?
