Question

Manufacturing of caustic soda by Castener Kellner cell

Answer 1

Answer:

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). ... The sodium deposited at mercury forms Sodium Amalgam. Chlorine produced at the anode is removed from the top of the cell.

Answer 2

Hey...

• 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.
