sodium would be produced at the anode of during the electrolysis of brine true or false?

Question

anonymous · Answer

ok so start of with anode and cathode charge, in electrolysis cathode is (-) and anode is (+) so if sodium needs an electron to have oxidation state 0 he would be deposited on which electrode?

anonymous · Answer

NaOH is produced at the cathode

anonymous · Answer

Actually, NaOH isn't produced at all.. Brine electrolysis breaks sodium chloride, dissolved in water, into chloride gas, hydrogen gas, hydroxide gas and sodium ions. Sodium ions are Na+ so it is still produced at the cathode.. Just not in the form of NaOH because there is water involved...

Hmm @aqua666 , unfortunately, NaOH is produced in the reaction. Because brine is a solution of NaCl in H2O, when electricity is passed, Na+ and Cl- dissociate, and Na+ joins up with the OH-  present in the solution as water molecules.(hydroxide ion) to form NaOH, which happens at the cathode.

However, in case of electrolysis of a pure NaCl sample (which happens in its molten form), pure Na is obtained.
