How is chlorine prepared by electrolytic method ? Explain its reaction

1.	How is chlorine prepared by electrolytic method ? Explain its reaction with NaOH
Answer» Preparation of chlorine by electrolytic method : Chlorine is obtained by the electrolysis of brine solutions (Conc. NaCl). `Cl_(2)` gas is liberated at anode. `2NaCl to2" Na"^(+)+2Cl^(-)` `2" H"_(2)O+2e^(-)to2OH^(-)+H_(2)` (cathode) `2" Cl"^(-) to Cl_(2)+2E^(-)` (anode) i) NaOH : Chlorine reacts with cold dil. NaOH to from sodium hypochlorite. `Cl_(2)+2" NaOH"to"NaCl"+"NaOCl"+H_(2)O` ii) `Cl_(2)` reacts with hot conc. NaOH to form sodium chloride and sodium chlorate. `3Cl_(2)+6" NaOH"to5" NaCl"+"NaClO"_(3)+3" H"_(2)O`

The heavier elements of groups 13 and 14 besides the group oxidation state exhibit another oxidation state which is two units lower than the group oxidation state and the stability of this lower oxidation state increases down the group. This concept which is commonly called inert pair effect has been used to explain many physical and chemical properties of the element of these groups. Element of group 13A. exhibit oxidation state of `+3` onlyB. form `M^(+)` and `M^(3+)` ionsC. exhibit oxidation states of +1 and +3D. form `M^(-)` and `M^(+)` ions
