Manufacturing Sodium Hydroxide: The Kellner-Solvay Cell

Question

Accepted Answer

The question asks for a technical explanation of the electrolysis of brine using a mercury cathode (the Kellner-Solvay process). You must explain the electrolytic principle, the specific role of the mercury cathode, the secondary reaction that produces the NaOH, and finally, identify the physical properties and the diverse industrial applications of the resulting product. The Kellner-Solvay process utilizes the electrolysis of a saturated aqueous solution of sodium chloride (brine). The core innovation here is the use of a flowing mercury cathode instead of a solid electrode. In standard electrolysis, hydrogen gas would normally be evolved at the cathode. However, mercury has a high overpotential for hydrogen discharge, meaning it requires more energy to produce hydrogen gas on a mercury s
