If an aqueous solution of $NaF$ is electrolysed between inert electrodes,the product obtained at anode is

Predict the products of electrolysis in each of the following:
$i$. An aqueous solution of $AgNO_3$ with silver electrodes
$ii$. An aqueous solution of $AgNO_3$ with platinum electrodes
$iii$. $A$ dilute solution of $H_2SO_4$ with platinum electrodes
$iv$. An aqueous solution of $CuCl_2$ with platinum electrodes.

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?

Give the electrolytic reaction of a concentrated aqueous $NaCl$ solution using inert electrodes.

The platinum electrodes were immersed in a solution of cupric sulphate and electric current was passed through the solution. After some time,it was found that the colour of copper sulphate disappeared with the evolution of gas at the electrode. The colourless solution contains:
