Sodium chloride

Description

Sodium chloride, NaCl, also known as common salt and halite, is a white crystalline solid.It is soluble in water,slightly soluble in alcohol, and melts at 804 °C (1480 °F). Sodium chloride is the most important sodium mineral and occurs naturally in seawater, underground deposits, and brine wells.Sodiumchlorideis a basic raw material for the production of chlorine,sodium hypochlorite, sodium bisulfate,soda ash, and hydrogen chloride. Sodium chloride is also used in food preparation, fertilizers

Sodium chloride appears as a white crystalline solid. Commercial grade usually contains some chlorides of calcium and magnesium which absorb moisture and cause caking.

Sodium chloride appears as a white crystalline solid. Commercial grade usually contains some chlorides of calcium and magnesium which absorb moisture and cause caking. (NTP, 1992)|Sodium chloride is an inorganic chloride salt having sodium(1+) as the counterion. It has a role as an emetic and a flame retardant. It is an inorganic chloride and an inorganic sodium salt.|Sodium chloride, also known as salt, common salt, table salt or halite, is an ionic compound with the chemical formula NaCl, representing a 1:1 ratio of sodium and chloride ions. Sodium chloride is the primary salt in seawater and in the extracellular fluid of many multicellular organisms. It is listed on the World Health Organization Model List of Essential Medicines.|Sodium Chloride is a metal halide composed of sodium and chloride with sodium and chloride replacement capabilities. When depleted in the body, sodium must be replaced in order to maintain intracellular osmolarity, nerve conduction, muscle contraction and normal renal function.|Saline is a solution of salt and water. Saline usually refers to normal or physiological saline, which is an aqueous solution containing 0.9% sodium chloride.|A ubiquitous sodium salt that is commonly used to season food.
