Manufacture of Compounds, Electrolysis of Brine

Manufacture of Compounds:

Pellets of sodium hydroxide are manufactured by the electrolysis of brine.

Electrolysis of Brine:

The electrolysis of brine yields hydrogen and chlorine at the electrodes.

The electrolytic cell used is known as the Kellner–Solvay cell. The anodeAn anode is an electrode of a polarized electrical device through which conventional current enters the device. It is the positive part of electrolytes where oxidation takes place. More is a carbon rod (graphite) dipped into the brine in the tank. A layer of mercury flowing at the base of the tank acts as the cathodeA cathode is the electrode from which a conventional current leaves the electrolyte. It is the negative part of the cell where reduction takes place. More.
