Sodium Chloride: Commonly Known as Salt

Salt acts as a biologically, necessary nutrient for human growth and development. If human beings did not give a damn about salt’s importance, our world would be filled with bland food, filthy water, and deadly disease. History’s first written records of salt appeared in China, around 4,700 years B.C.E. Salt played a major role in ancient history, especially in Roman and Egyptian cultures. Citizens of Rome and Egypt commonly used salt as trade goods, currency for soldiers, religious offerings, and

is a chemical named sodium chloride (NaCl), more commonly known as road salt. According to New Hampshire Department of Environmental Services, the first step to melting ice is to brine, this is a process where salt crystals “pull out” water molecules from their ice formations. Once the brine is applied to the ice, it is able to expedite the melting process. However, this application can only be applied when the temperature is above 15° F. This

would send trucks go around the roads and spread a mixture of salt and sand so that the ice would melt quickly than usual. People would also use deicers for the same reasons at their home and their neighborhoods. In 2008, U.S. consumption of salt for deicing was 22.6 Mt, which was about 9% more than that of 2007. It required more rock salt usage because of the greater winter precipitation in late 2008. The United States produced more salts than any other countries in the world until the year of 2005

Chlorine is a widely known element found in salt, cleaning agents, antibacterial agents, and some dyes. Chlorine is an extremely reactive halogen, its chemical symbol is Cl, and its atomic mass is 35.45. The element’s atomic number is 17, and its density is 0.003214 g per cubic cm. Chlorine is not a free element, but it is sometimes found in volcanic gas. The element is mostly found in other compounds, and when extracted, is a dense gas that is heavier than air; its color is a greenish-yellow. The

Variable (Sodium Chloride) The manipulated variable in our project is sodium chloride, commonly known as salt. Sodium chloride is a cube-shaped mineral that is mined all over the world. It is known scientifically as NaCL, and it is made up of 40% sodium and 60% chlorine. Sodium chloride is essential to most living things on Earth. For example, the intake of sodium chloride is essential for the survival of plants. All plants can absorb sodium chloride, but some are more tolerant of sodium chloride than

material in order to achieve the desired level of service (LOS). The strategy most commonly used now is the application of chemical de-icers. After a road is first plowed, de-icing chemicals are applied to the road surface. De-icers applied onto roadways often contain chlorides as freezing-point depressants due to their cost-effectiveness, including mainly sodium chloride (NaCl), magnesium chloride (MgCl2), and calcium chloride (CaCl2). Sometimes, they are blended with proprietary corrosion inhibitors.

Sodium is one of the most well known and abundant yet fascinating elements on the periodic table. Sodium was given its name after a chemist who electrolytically produced a heretofore unknown element from molten soda. This gave him the new element that he named sodium after the word soda which is the collective name for several forms of sodium carbonate. The word “soda” likely came from the Arabic word “suda” which means headache. This element has eleven protons, eleven neutrons, and no electrons

the most known, such as oxygen, to some of the most unknown, protactinium. Out of these 118 element I think the most important one is sodium(Na). Sodium is is a soft metal at room temperature and is in the first group, which are the Alkali Metals (1). It’s atomic number is eleven and it is in the third period on the periodic table (1). Sodium is used in many different compounds such as sodium chloride, sodium carbonate, and sodium hydroxide. Sodium does a great deal of things like salt our food

who discovered many elements in the history of science. He was one of those people who never took any credits in his favor. The element chlorine was discovered by him in 1774, when he reacted hydrochloric acid (HCL- a solution made up of hydrogen chloride) with manganese dioxide (MnO2). 4HCl + MnO2 - MnCl2 + 2H2O + Cl2 According to Jack challoner, in his book “The elements” he says, after the reaction has occur “Scheele noted that gas produced by the

of solutions that depend on the number of dissolved particles in solution, but not on the identities of the solutes. For example, the freezing point of salt water is lower than that of pure water, due to the presence of the salt dissolved in the water. To a good approximation, it does not matter whether the salt dissolved in water is sodium chloride or potassium nitrate; if the molar amounts of solute are the same and the number of ions are the same, the freezing points will be the same.
