Question

The products of chloro-alkali process are ______.

विकल्प

• NaCl, Cl₂ and H₂

• H₂, Cl₂ and NaOH

• Cl₂, Na₂CO₃ and H₂O

• NaOH, Cl₂ and HCl

Answer 1

H₂, Cl₂ and NaOH

Explanation:

The chlor-alkali process is the electrolysis of a concentrated aqueous solution of sodium chloride, commonly known as brine (NaCl + H₂O). During electrolysis, chlorine gas (Cl₂) is liberated at the anode, while hydrogen gas (H₂) is released at the cathode. Sodium hydroxide (NaOH), an alkaline solution, is left behind in the electrolyte chamber, giving the process its name (chlor for chlorine and alkali for sodium hydroxide).
