Sodium amalgam
[5] The process causes localised boiling of the mercury and for this reason the formation is usually conducted in a fume hood and often performed using air-free techniques, such as synthesis under anhydrous liquid paraffin.Sodium amalgam is a by-product of chlorine made by mercury cell electrolysis.In this cell, brine (concentrated sodium chloride solution) is electrolysed between a liquid mercury cathode and a titanium or graphite anode.Normally this sodium amalgam is drawn off and reacted with water in a "decomposer cell" to produce hydrogen gas, concentrated sodium hydroxide solution, and mercury to be recycled through the process.In principle, all the mercury should be completely recycled, but inevitably a small portion goes missing.
