Question

Write the reaction of this :

formation of sodium hydroxide from aqueous solution of sodium chloride​

Answer 1

Answer:

Sodium hydroxide is produced (along with chlorine and hydrogen) via the chloralkali process. This involves the electrolysis of an aqueous solution of sodium chloride. The sodium hydroxide builds up at the cathode, where water is reduced to hydrogen gas and hydroxide ion: 2Na+ + 2H2O + 2e− → H2 + 2NaOH.
