At the anode in the electrolysis of fused $NaCl$,what happens?

The electroplating of $Cr$ is undertaken because:

Write the reactions for the following:
$A$. Electrolytic reaction of concentrated and dilute solution of $H_2SO_4$.
$B$. Oxidation reaction of $SO_4^{2-}$.

In the electrolysis of aqueous copper sulphate $(CuSO_4)$ using inert electrodes,the gases evolved at the anode and cathode are,respectively:

Name the processes from which chlorine is obtained as a by-product. What will happen if an aqueous solution of $NaCl$ is subjected to electrolysis?

Electrolysis of a concentrated aqueous solution of $NaCl$ with graphite electrodes leads to what results at the anode and cathode respectively?
