On the electrolysis of aqueous solution of sodium sulphate,at the cathode we get:

The number of electrons passing per second through a cross-section of copper wire carrying $10^{-6} \ A$ of current is found to be:

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

$KOOC-CH_2-CH_2-COOK \xrightarrow{\text{electrolysis}} (A) (\text{major})$. Product $(A)$ is:

Chlorine can be manufactured from
