A Chloralkali Cell

We do our best to make a final, comprehensive video on the diaphragm chloralkali process by building a cell capable of making moderate quantities of sodium/potassium hydroxide. This particular cell is capable of converting sodium chloride into sodium hydroxide at a current efficiency of 15-20%. At one amp of current (and a voltage of about 6-7 volts), we generate about 50g of NaOH per kWh, and under my price for electricity, that comes out to a production cost of $5 per kilogram of NaOH (a profitable process if all I need is NaOH solution rather than the solid stuff). The cell will be useful in the future for the production of sodium hydroxide, potassium hydroxide, chlorine, hydrogen, and possibly hydrochloric acid eventually.
