Answer to Question #102329 in General Chemistry for Muktar

Question

What is the electrolysis of sodium hydroxide using macury electrode

Answer 1

In the mercury-cell process, also known as the Castner–Kellner process, a saturated brine solution floats on top of a thin layer of mercury. The mercury is the cathode, where sodium is produced and forms a sodium-mercury amalgam with the mercury. The amalgam is continuously drawn out of the cell and reacted with water which decomposes the amalgam into sodium hydroxide, hydrogen and mercury.
