What are the various uses of mercury?
Answers
Answer:
Mercury is used in laboratories for making thermometers, barometers, diffusion pumps, and many other instruments. It is used for mercury switches and other electrical apparatus. It is used as an electrode in some types of electrolysis and for making batteries (mercury cells).
Explanation:
Vials of pure mercury have been found in Egyptian tombs from the 1500s BCE. Mercury is used in fluorescent lamps, thermometers, float valves, dental amalgams, in medicine, for the production of other chemicals, and to make liquid mirrors.
Although many liquids could be used in pressure measuring devices, mercury is used because its high density requires less space. It is also a good conductor of electricity, so it is a useful component of electrical switches. Mercury is also used in dental fillings, paints, soaps, batteries, and fluorescent lighting.
MERCURY HAS LONG BEEN USED as a medicine to treat various diseases, such as syphilis and typhoid fever, or parasites. Certainly a treatment with such a "powerful" medicine impressed patients, and when poisoning symptoms appeared they could always be blamed on worsening of the original disease.
Elemental and methylmercury are toxic to the central and peripheral nervous systems. The inhalation of mercury vapour can produce harmful effects on the nervous, digestive and immune systems, lungs and kidneys, and may be fatal.
