Mercury Hg

Mercury is a relatively rare chemical element. In the lithosphere it occurs mainly as sulfides, HgS. Mercury sulfide comes in two forms cinnibar, which is black, and vermillion. In some places mercury exists in a small proportion as free chemical species. 

Liquid mercury is quite easily oxidized at anodic potentials (when immersed in water) so most of the measured current would be due to the reaction Hg -> Mercury is electrochemically stable for a... 

Mercury (Hg) Mercury is a silvery white liquid metal. Because of its high density, mercury is used in sphygmomanometers. It is also found in some thermometers. Before its toxic nature was fully understood, mercury compounds had been used in medical applications ranging from treatment of syphilis to constipation. Mercury alloys well with many other metals, and alloys containing mercury are known as amalgams. 

Figure 19.18 Two metals (liquid at room temperature) were used as top electrode. Hg (Mercury) provides bad wetting on the PZT surface (figure left) and therefore insufficient electric contact. Ga (Gallium) shows quite good wetting properties on the PZT surface (drops deposited at about 60°C) enabling reasonable P-loops measurements and fatigue onset.
