उत्तर
The products of chloro-alkali process are 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).
