Talk:Sodium hydroxide

Parked here for reinsertion after project completion.

Electrolysis
Sodium hydroxide is produced commercially by electrolysis, sending a direct current through an aqueous solution of sodium chloride. Hydrogen gas is released at the negative pole and chlorine gas is released at the positive pole. At the end of the electrolysis, the solution contains sodium hydroxide. The process is illustrated above:

2NaCl(aq) + 2H2O(l) -(electrolysis)-> H2(g) + Cl2(g) + 2NaOH(aq)
