Extraction of chlorine from brine solution is based on

Answer»

aciditication
reduction
OXIDATION
chlorination.

Solution :Chlorine can be manufactured by ELECTROLYSIS of a sodium chloride solution (brine). Electrolysis of brine solution involves the FOLLOWING reactions:
At CATHODE:
`2H_(aq)^(+)+ 2e^(-) to H_(2(g))`(Reduction)
At anode:
`2Cl_(aq)^(-) to Cl_(2(g))+ 2e^(-)` (Oxidation)
Overall reaction:
`2NaCl_(aq)+ 2H_(2)O_(L) to Cl_(2(g))+ H_(2(g))+2NaOH_(aq)`
