Hi there,
◇ Electrolysis of NaCl solution produces
● chlorine gas at anode
●` hydrogen gas at cathode
● Forming sodium hydroxide at cathode
◇ In industry its called electrolysis of brine
●Equations
☆At anode (+)
2Cl- => Cl2 + 2e
☆At cathode (-)
2H2O + 2e => H2 + 2OH
☆Total cathode equation
(2Na+) +2H2O=> H2 + (2Na+) + (2OH-)
☆The total process equation
2NaCl + 2H2O=> Cl2+H2+2NaOH
◇ Due to formation of chlorine gas and sodium hydroxide the process called chlor alkali process
♡ Hope the answer is helpful
♡ Plz mark it as brailiest answer
