The cell used for the electrolysis of fused $NaCl$ is

Describe the method of obtaining chlorine from brine (sea water) and write the oxidation-reduction reactions,specifying the products at the anode and cathode.

$O_2$ gas will be evolved as a product of electrolysis of $:$
$(A)$ an aqueous solution of $AgNO_3$ using silver electrodes.
$(B)$ an aqueous solution of $AgNO_3$ using platinum electrodes.
$(C)$ a dilute solution of $H_2 SO_4$ using platinum electrodes.
$(D)$ a high concentration solution of $H_2 SO_4$ using platinum electrodes.
Choose the correct answer from the options given below $:$

Electrolysis of aqueous $Na_2SO_4$ was carried out by passing a current of $3 \ A$ for $10 \ min$. The volume of the gas $(L)$ at $STP$ at the anode of the cell is approximately

Explain: Oxidation of $Cl^{-}$ ion is carried out near the anode when electrolysis of aqueous (concentrated) $NaCl$ solution is carried out using an inert electrode.

During the electrolysis of molten sodium chloride,the electrode reactions are:
