Mercury cathode
WebA mercury battery (also called mercuric oxide battery, or mercury cell) is a non-rechargeable electrochemical battery, a primary cell. Mercurybatteries use a reaction between mercuric oxide and zinc electrodes in an alkaline electrolyte. Mercury cell is a new type of dry cell. It consists ofAnode: Zinc-mercury.Cathode: Paste of HgO and … Webhigh overpotential for H+ reduction to H2 at the mercury surface o H+ reduction does not interfere with many reductions; no memory effects; yields reproducible current-potential data; working range: ≈ 0 V and -2 V (depending on conditions) Hg→Hg+2+2e- +0 (depending on the medium) 2H+ +2e- →H2 -0 to – 2V (depending on pH and medium)

WebCathodes designed for mercury arc lamps are cone-shaped rods (see Figure 2) fabricated from thoriated (thorium oxide) tungsten to improve starting and emission characteristics as well as to lower the open-circuit … WebIn this cell, brine (concentrated sodium chloride solution) is electrolysed between a liquid mercury cathode and a titanium or graphite anode. Chlorine is formed at the anode, while sodium formed at the cathode dissolves into the mercury, making sodium amalgam.
