What is mercury?
It's a silver mine. It is liquid in normal temperature. The symbol «Hg» has a specific gravity of 13.59. The boiling point is 357 °, the freezing point is 39 °, the atomic number is 80 and the atomic weight is 200.61.
Mercury is found in Spain, Italy, California, Mexico and Peru. There are also in our country. In order to obtain mercury, the chain is decomposed into sulfur dioxide and mercury vapor. When mercury vapors are concentrated, mercury is obtained in liquid form. Mercury vapor is colorless. When it is poured into the ground it is always collected in round drops.
Mercury does not change in moist and dry air. Since it is not affected by temperatures below 300 °, it is used in the construction of instruments such as thermometer and barometer, in the seperation, in the extraction of gold and silver mines, and the toxic salts are used in the production of a number of germ chemicals.
It is the only metal which is liquid at room temperature. Civa's symbol in the periodic table is "Hg". The atomic number is 80. The symbol "Hg" comes from the word hydrargyrum in Latin. Due to the very high freezing point of mercury, it is in liquid state under normal conditions.
Where is Civa used?
For 3500 years, mankind has been trying to use mercury for industrial and agricultural purposes. Mercury is also used in mushroom killing. Mercury compounds are used in agriculture and paper industry, plastic, battery, paint industry. It is used in thermometers, manometers and rectifiers. mercury is used in the construction of neon lights.
What are the damages if the mercury is harmful?
Mercury is carcinogenic. It's an expensive element. It is very dangerous because it is an inhibitor. Organic mercury compounds are important but dangerous. For example; methyl mercury is a lethal contaminant that can be found in rivers and lakes. Mercury is a toxic substance; Absorbed through the respiratory, stomach and skin. Since there is very little way for its excretion from the body, it is an increased poison by accumulating effect. mercury is a volatile element. Harmful for long periods of inhalation.
Mercury damages developing nervous systems in humans. Mercury cannot be removed from the body and mercury vapor passes through the cell membrane and reaches the brain. Mercury vapor settled in all tissues, if accumulated in tissues over time, causes non-transformational neurological findings. These can lead to death. Even in the event of timely diagnosis, the treatment can not eliminate the findings. To address the damages of Civa:
1. Causes nervous system disorders.
2. It damages brain functions.
3. It damages the DNA and chromosomes.
4. It causes allergic reactions, skin rash, fatigue and headache.
5. It causes negative effects on reproduction; damage to sperm, birth defects and miscarriage.
6. Damage to brain function leads to learning disability, personality changes, tremors, visual disturbances, deafness, loss of muscle coordination, and memory loss.
7. Damage to chromosomes leads to mongolism.
What should be done when mercury is spilled?
When mercury is poured on any surface, powder sulfur should be poured on it. And care must be taken when cleaning the resulting mixture.
Where is Civa located?
Mercury is found in several forms in air, water and soil. These are in the form of elemental mercury, inorganic and organic mercury compounds. The mercury is sometimes found as natural droplets in the sprouting layer of the sprout. The use of fossil fuels such as coal and oil, mining, metallurgy, steel and cement production lead to the emergence of mercury.
What is Elementel mercury?
Elemental or metallic mercury is a shiny, silver-white metal and liquid at room temperature. The specific weight is 13.6 gr / cm3, the atomic number is 80 and the atomic weight is 200.61. It evaporates not only when heated, but also at room temperature. Mercury vapors are toxic. The most important mineral of mercury is sinober (ginger) (HgS).
What are mercury salts?
Inorganic mercury compounds, or more commonly known mercury salts, are generally white powder or crystalline. Only the mercury sulfur compound is red in color. The melting point of mercury is -38.8 ºC and the boiling point is 356.58 ºC. Although the thermal conductivity is poor, the electrical conductivity is quite good. Mercury easily alloy with other metals. These alloys are called amalgam. mercury can be combined with electric current to combine with noble gases such as neon, argon, krypton, xenon.
