Question

Name the commercial method by which NaOH is obtained? Name other two products obtained.​

Answer 1

Answer:

Sodium hydroxide is industrially produced as a 50% solution by variations of the electrolytic chloralkali process. Chlorine gas is also produced in this process. Solid sodium hydroxide is obtained from this solution by the evaporation of water

Answer 2

NaOH is commercially obtained by the electrolytic chloralkali process.

• Sodium hydroxide is industrially produced as a 50% solution by variations of the electrolytic chloralkali process.
• Chlorine gas is also produced in this process. Solid sodium hydroxide is obtained from this solution by the evaporation of water.
• It is generally prepared by electrolysis of sodium chloride in the Castner-kellner cell. A brine solution is electrolyzed using mercury cathode and carbon anode.
• The other two products obtained are chlorine and hydrogen gas.
