what is a water mercury

[59] Last, but not least, the triple point of mercury, −38.8344 Â°C, is a fixed point used as a temperature standard for the International Temperature Scale (ITS-90).[5]. All four mercuric halides are known. [5], It has a freezing point of −38.83 Â°C and a boiling point of 356.73 Â°C,[6][7][8] both the lowest of any stable metal, although preliminary experiments on copernicium and flerovium have indicated that they have even lower boiling points (copernicium being the element below mercury in the periodic table, following the trend of decreasing boiling points down group 12). Recent data show that water ice may exist in the bottoms of craters at Mercury's poles. [93] Protocols call for physically merging smaller droplets on hard surfaces, combining them into a single larger pool for easier removal with an eyedropper, or for gently pushing the spill into a disposable container. Many historic applications made use of the peculiar physical properties of mercury, especially as a dense liquid and a liquid metal: Others applications made use of the chemical properties of mercury: Mercury(I) chloride (also known as calomel or mercurous chloride) has been used in traditional medicine as a diuretic, topical disinfectant, and laxative. Treatment of Hg(I) compounds complexation with strong ligands such as sulfide, cyanide, etc. Environmental dangers have been a concern, particularly in the southern cities of Foshan and Guangzhou, and in Guizhou province in the southwest. [120] Acute exposure to mercury vapor has been shown to result in profound central nervous system effects, including psychotic reactions characterized by delirium, hallucinations, and suicidal tendency. [66], Mercury, as thiomersal, is widely used in the manufacture of mascara. Mercury is a highly toxic element that is found both naturally and as an introduced contaminant in the environment. For example, Williston Lake in northern British Columbia, created by the damming of the Peace River in 1968, is still sufficiently contaminated with mercury that it is inadvisable to consume fish from the lake. We drip mercury into a contain of water and also stir the concoction to create a vortex. It is found either as a native metal (rare) or in cinnabar, metacinnabar, corderoite, livingstonite and other minerals, with cinnabar (HgS) being the most common ore.[27][28] Mercury ores usually occur in very young orogenic belts where rocks of high density are forced to the crust of Earth,[citation needed] often in hot springs or other volcanic regions. Symptoms typically include sensory impairment (vision, hearing, speech), disturbed sensation and a lack of coordination. The price of mercury has been highly volatile over the years and in 2006 was $650 per 76-pound (34.46 kg) flask. "[139], Products containing mercury were banned in Sweden in 2009.[140][141]. Mercury is officially classed as a mineral species for historical reasons, and also because it is distinctive in its chemical and physical properties. The patio process and later pan amalgamation process continued to create great demand for mercury to treat silver ores until the late 19th century. Despite claims otherwise,[37] Hg(III) and Hg(IV) compounds remain unknown.[38][39]. Water as from such a source in terrestrials comes from hydrogen and oxygen trapped in the mantle material, which are later released by volcanism and reconstituted as water sooner or later. Mercury and most of its compounds are extremely toxic and must be handled with care; in cases of spills involving mercury (such as from certain thermometers or fluorescent light bulbs), specific cleaning procedures are used to avoid exposure and contain the spill. These include Millon's base (Hg2N+), the one-dimensional polymer (salts of HgNH+2)n), and "fusible white precipitate" or [Hg(NH3)2]Cl2. The type and degree of symptoms exhibited depend upon the individual toxin, the dose, and the method and duration of exposure. It reacts with chlorine to give mercuric chloride, which resists further oxidation. Because this configuration strongly resists removal of an electron, mercury behaves similarly to noble gases, which form weak bonds and hence melt at low temperatures. HgCl2 forms coordination complexes that are typically tetrahedral, e.g. Cleaning porous surfaces and clothing is not effective at removing all traces of mercury and it is therefore advised to discard these kinds of items should they be exposed to a mercury spill. [18][19] Khumarawayh ibn Ahmad ibn Tulun, the second Tulunid ruler of Egypt (r. 884–896), known for his extravagance and profligacy, reportedly built a basin filled with mercury, on which he would lie on top of air-filled cushions and be rocked to sleep. [51] Mercury is still used in some diuretics although substitutes now exist for most therapeutic uses. Water run-off from such sites is a recognized source of ecological damage. [25], Mercury is an extremely rare element in Earth's crust, having an average crustal abundance by mass of only 0.08 parts per million (ppm). The richest mercury ores contain up to 2.5% mercury by mass, and even the leanest concentrated deposits are at least 0.1% mercury (12,000 times average crustal abundance). [62] Gaseous mercury is also found in some electron tubes, including ignitrons, thyratrons, and mercury arc rectifiers. For example, the amount of mercury sold in thermostats in the United States decreased from 14.5 tons in 2004 to 3.9 tons in 2007.[103].
