Electrolysis of aqueous sodium chloride. Electrolysis of aqueous NaCl results in hydrogen and chloride gas. At the anode (A), chloride (Cl-) is oxidized to chlorine. The ion-selective membrane (B) allows the counterion Na+ to freely flow across, but prevents anions such as hydroxide (OH-) and chloride from diffusing across.

Feb 28, 2018 Before mercury was recovered from the solution by electrolysis, copper was removed by increasing the solution pH to 4.5 with calcium or sodium carbonate. Iron present in the leaching solution was also precipitated at pH 4.5. Failure to remove copper caused sludges to build up on the mercury cathode and decreased current efficiency to 30 pct.

Chloride ions and hydroxide ions (from the water) arrive. The chloride ions are discharged to form chlorine gas. 2Cl-(aq) Cl 2 (g) + 2e-Warning! This is a bit of a simplification. What you get depends on the concentration of the solution. If you have reasonably concentrated sodium chloride solution, you do in fact get chlorine produced.
