Sodium chloride (chemical formula NaCl) is an inorganic salt formed by the ionic bonding of sodium and chloride ions.
It has a molecular weight of 58.44 g/mol and a solubility in water of 360 g/l[1].
It is the largest dissolved constituent of seawater and is mass produced by the evaporation of seawater in salt farms or by the mining of rock salt[2].
Sodium chloride produced in this way will always containt impurities from other ions in seawater.
Pure sodium chloride can be produced by reacting sodium metal with chlorine gas[3].
