HOW IS CAUSTIC SODA MANUFACTURED??
shonakhan55:
Chlorine gas is also produced in this process. Solid sodium hydroxide is obtained from this solution by the evaporation of water. Principle — In castner-kellner method NaOH is prepared by the electrolysis of aqueous solution of NaCl (Brine)

Caustic soda is prepared by passing electricity through aqueous solution of sodium chloride or brine.
That is,caustic soda is prepared by the electrolysis of brine.
This process is also known as chlor-alkali process because of the products formed where chlor refers to chlorine and alkali refers to sodium hydroxide.
Chlorine gas will be liberated at anode and hydrogen gas at the cathode.
Sodium hydroxide that is the caustic soda is formed near the cathode.

Nearly all caustic soda is generated by the electrolysis of sodium chloride solution using one of three cell types: mercury, diaphragm and membrane cells. The electrolysis process produces 2.25 tonnes of 50% caustic soda with each tonne of chlorine. ... The sodium chloride solution is often called brine.2010
