CAS number : 7647-14-5
Molecular weight :58.44
Molecular formula/chemical symbol :NaCl
Description :
Sodium chloride, also known as common salt, table salt, or halite, is a chemical compound with the formula NaCl. Sodium chloride is the salt most responsible for the salinity of the ocean and of the extracellular fluid of many multicellular organisms. As the major ingredient in edible salt, it is commonly used as a condiment and food preservative. In one gram of sodium chloride, there are approximately 0.3933 grams of sodium, and 0.6067 grams of chlorine.
Keywords：Chloride
USES :
Synthetic uses:Salt is also the raw material used to produce chlorine which itself is required for the production of many modern materials including PVC and pesticides.
Flavor enhancer:Salt is commonly used as a flavor enhancer for food and has been identified as one of the basic tastes. Unfortunately, it is often ingested well in excess of the required intake. This leads to elevated levels of blood pressure (hypertension) in some, which in turn is associated with increased risks of heart attack and stroke. Consuming salt in excess can also dehydrate the human body.
Biological uses:Many microorganisms cannot live in an overly salty environment: water is drawn out of their cells by osmosis. For this reason salt is used to preserve some foods, such as smoked bacon or fish, and can also be used to detach leeches that have attached themselves to feed. It has also been used to disinfect wounds (although it causes a great deal of pain). In medieval times, salt would be rubbed into household surfaces as a cleansing agent
