MERCURY Chemical Properties,Uses,Production


Although mercury is known from early times and was used by alchemists, its first modern scientific applications date back to 1643 when Torricelli used it in the barometer to measure pressure and about eight decades later Fahrenheit used it in the thermometer to measure temperature. Before this, mercury’s use was confined to decorative work, gold extraction and medicines. The element was named after the planet mercury and its symbol Hg is taken from the Latin word hydrargyrum, which means liquid silver.
The element does not occur in nature in native form. Its principal mineral is cinnabar, the red mercuric sulfide, HgS. Black mercuric sulfide, metacinnabar, also is found in nature. Other ores are livingstonite, HgSb4S7; coloradite, HgTe; tiemannite, HgSe; and calomel, HgCl. Its concentration in the earth’s crust is estimated to be 0.08 mg/kg. The average concentration in sea water is about 0.03 µg/L.


Some of the most important uses of mercury are in the electrical and electrolytic applications. A broad range of such applications include mercury batteries and cells in portable radios, microphones, cameras, hearing aids, watches, smoke alarms, and wiring and switching devices. Other notable applications are in mercury vapor lamps, fluorescent tubes and electrical discharge tubes. Mercury electrodes are widely used in electrolytic cells. Mercury cathodes are employed in the electrolysis of sodium chloride to produce caustic soda and chlorine. Another major use, as mentioned earlier, is in thermometers, manometers, barometers and other pressure-sensing devices. Mercury also is used as a catalyst in making urethane foams and vinyl chloride monomers. Mercury and its compounds long have been used as fungicides in paints and in agriculture. Mercury compounds are used in medicines, pigments and analytical reagents.
In mercury arc lamps producing ultraviolet rays; in mercury boilers; manufacture of all mercury salts, mirrors; as catalyst in oxidation of organic Compounds; extracting gold and silver from ores; making amalgams, electric rectifiers, mercury fulminate; also in dentistry; in determining N by Kjeldahl method, for Millon's reagent; as cathode in electrolysis, electroanalysis, and many other uses. Also in pharmaceuticals, agricultural chemicals, anti-fouling paints.

Production Methods

Mercury mostly is obtained from its sulfide ore, cinnabar. The process involves roasting cinnabar in a furnace between 600 to 700°C. Mercury vapors are cooled and condensed into metal:
HgS + O2 → Hg + SO2
Mercury may also be extracted from cinnabar by reduction of the ore with lime at elevated temperature:
4HgS + 4CaO → 4Hg + 3CaS + CaSO4
Smaller quantities of metal are recovered from mercury-containing industrial and municipal wastes, such as amalgams and batteries. The scrap material is heated in a retort and the vapors of mercury are condensed into highpurity metal.


Elemental mercury and all its compounds are highly toxic by all routes of exposure. The element has significant vapor pressure at ambient temperatures (0.0018 torr at 25°C) that can produce severe inhalation hazard. The symptoms from short exposure to high concentration of mercury vapors are bronchitis, coughing, chest pain, respiratory distress, salivation and diarrhea (Patnaik, P. 1999. A Comprehensive Guide to the Hazardous Properties of Chemical Substances, 2nd ed., New York: John Wiley and Sons). Other symptoms are tremor, insomnia and depression. Mercury can cause damage to kidney, liver, lungs and brain. Organomercury compounds and inorganic salt solutions can be absorbed into the body through skin contact and cause severe poisoning. It accumulates as Hg2+ in the brain and kidneys. US EPA has classified mercury as one of the priority pollutant metals in environmental matrices.

Reactivity Profile

MERCURY forms an explosive acelylide when mixed with acetylene. Can form explosive compounds with ammonia (a residue resulting from such a reaction exploded when an attempt was made to clean MERCURY off a steel rod [Chem. Eng. News 25:2138. 1947]. Chlorine dioxide (also other oxidants, such as: chlorine, bromine, nitric acid, performic acid), and MERCURY explode when mixed [Mellor 2, Supp. 1:381. 1956]. Methyl azide in the presence of MERCURY is potentially explosive [Can. J. Chem. 41:1048. 1963]. Ground mixtures of sodium carbide and MERCURY can react vigorously [Mellor 5:848. 1946-47]. Ammonia forms explosive compounds with gold, MERCURY, or silver. (Eggeman, Tim. mmonia Kirk-Othmer Encyclopedia of Chemical Technology. John Wiley & Sons, Inc. 2001.).

Health Hazard

Mercury is a non-specific toxin, attacking many of the body s systems. At low levels of exposure, symptoms are mainly related to nerve and brain function and include memory loss, mood instability, tremor, and other stress-like symptoms: poor coordination, headache, and visual and hearing problems. Recently, reproductive health has been shown to be affected, with abnormalities in menstrual cycle, poor outcome of pregnancy, and subfertility in both men and women. The immune system is also damaged by mercury exposure.

Health Hazard

ngestion is largely without effects. Inhalation of high concentrations of mercury causes severe respiratory irritation, digestive disturbances, and marked kidney damage. There are no warning properties for exposure to mercury vapor, which is colorless, odorless, and tasteless.
Toxicity caused by repeated or prolonged exposure to mercury vapor or liquid is characterized by emotional disturbances, inflammation of the mouth and gums, general fatigue, memory loss, headaches, tremors, anorexia, and weight loss. Skin absorption of mercury and mercury vapor adds to the toxic effects of vapor inhalation. At low levels the onset of symptoms is insidious; fine tremors of the hand, eyelids, lips, and tongue are often the presenting complaints. Mercury has been reported to be capable of causing sensitization dermatitis. Mercury has not been shown to be a human carcinogen or reproductive toxin

Health Hazard

Elemental mercury and its inorganic salts,as well as organomercury compounds, areall highly toxic substances. The elementhas a vapor pressure of 0.0018 torr at 25°C(77°F), which is high enough to make it asevere inhalation hazard. Exposure to mercuryvapors at high concentrations for ashort period can cause bronchitis, pneumonitis,coughing, chest pain, respiratory distress,salivation, and diarrhea. The toxic symptomsdue to its effects on the central nervous systeminclude tremor, insomnia, depression, and irritability.A 4- hour exposure to mercury vaporsat a concentration of about 30 mg/m3 in airproduced damage in the kidneys, liver, lungs,and brain in rabbits (ACGIH 1989). Elementalmercury is rapidly oxidized to Hg(II) in redblood cells. Prior to its oxidized and accumulates(Manahan 1989). Mercury(II) accumulatesin the kidneys.
The toxicity of mercury depends on itschemical form the target organs, symptomsand signs may differ with exposureto elemental mercury its inorganic compoundsor organic mercury. The toxicities of mercurycompounds show significant variation withsolubility. Less soluble mercurous compoundsare relatively less toxic than themore soluble mercuric salts. The latter compoundsare highly toxic ingestion. Chroniceffects due to Hg(II) ions are inflammationof the muth, salivation, loose teeth, muscletremors, jerky gait, depression, irritability,and nervousness (Hodgson et al. 1988). TheHg2C ions have an affinity for sulfhydrylgroups ( SH) in proteins, enzymes, serumalbumin, and hemoglobin to form complexes,thereby causing enzyme inhibition.Cycteine, penicillamine, and 2,3-dimercapto-1-propanol are effective antidotes againstmercury(II) poisoning. Also reported are theother sulfur antidotes; unithiol ,BAL , and D-penicillamine [52-67-5] (Softova et al. 1984). These substancescan form chelates with mercury and excreteout in the urine, thus exhibiting a protectiveeffect against mercury-induced renaldamage. N-Benzyl-D-glucamine is anotherchelating agent that has shown protectiveaction against renal toxicity of inorganic mercuryin rats (Kojima et al. 1989).
Endo et al. (2003) investigated therenal toxicity in rats caused by a singleoral administration of mercury-contaminatedboiled whale livers that contained both theinorganic mercury and dimethylmercury. Theconcentration of mercury in the rat kidneyincreased markedly after the dose, so alsothe urinary excretion of N-acetyl-beta-Dglucosanidase,albumin, and sodium. Also,the concentrations of creatinine, potassium,and phosphorus in the serum and the lactatedehydrogenase activity increased. The studyshowed that the renal toxicity was causedby inorganic mercury and that the humanconsumption of boiled whale liver couldcause acute intoxication from contaminatedinorganic mercury.
Several studies have been carried out todetermine the adverse health effects fromhuman exposure to mercury from dentalamalgam (Ratcliffe et al. 1996; Krupa 2004).However, all findings are inconclusive. Theevidences found are insufficient to drawa link between dental mercury fillingsand human health problems except in rareinstances of allergic reactions.

First aid

If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medical attention. Give large quantities of water and do induce vomiting. Do not make an unconscious person vomit.
Antidotes and Special Procedures for medical personnel: The drug NAP has been used to treat mercury poisoning, with mixed success


Precautions should be taken to prevent spills of mercury because drops of the liquid metal can easily become lodged in floor cracks, behind cabinets, and equipment, etc., with the result that the mercury vapor concentration in the laboratory may then exceed the safe and allowable limits. Containers of mercury should be kept tightly sealed and stored in secondary containers (such as a plastic pan or tray) in a well-ventilated area. When breakage of instruments or apparatus containing significant quantities of Hg is possible, the equipment should be placed in a plastic tray or pan that is large enough to contain the mercury in the event of an accident. Transfers of mercury between containers should be carried out in a fume hood over a tray or pan to confine any spills.

Purification Methods

After air has been bubbled through mercury for several hours to oxidise metallic impurities, it is filtered to remove coarser particles of oxide and dirt, then sprayed through a 4-ft column containing 10% HNO3. It is washed with distilled water, dried with filter paper and distilled under vacuum. [Schenk in Handbook of Preparative Inorganic Chemistry (Ed. Brauer) Academic Press Vol I p8 1963.]


Heating mercury causes the formation of toxic mercury oxide fumes. Reacts violently with alkali metals; acetylene, azides, ammonia gas; chlorine, chlorine dioxide; many acids; most metals; ground mixtures of sodium carbide, and ethylene oxide. Contact with methyl azide forms shock- and spark-sensitive explosives. Attacks copper and many other metals, forming amalgams

Waste Disposal

Consult with environmental regulatory agencies for guidance on acceptable disposal practices. Generators of waste containing this contaminant (≥100 kg/mo) must conform to EPA regulations governing storage, transportation, treatment, and waste disposal. Accumulate for purification and re-use if possible. Mercury vapors may be adsorbed or treated with sulfide solutions and then sent to mercury recovery operations
