Sodium Chloride CAS#7647-14-5
Products Description of Sodium chloride CAS#7647-14-5
Sodium chloride is widely found in nature. Oceans are its largest source, with an average concentration of 2.68% by weight in seawater. It also exists in many inland saltwater bodies and in salt deposits within sedimentary rocks—where it appears as the mineral halite. Sodium chloride is likely the most important salt for both sodium and chlorine. Known as common table salt, it is an essential ingredient in most food preparation: it adds flavor to food and meets the body’s nutritional need for sodium.

Product Application of Sodium chloride CAS#7647-14-5
Sodium chloride, commonly called table salt, occurs naturally as the mineral halite, and is also present in brines and seawater. It dissolves in water but has lower solubility in alcohol. Historically, it was the first halide to be combined with silver nitrate; additionally, L. J. M. Daguerre and W. H. F. Talbot used it as a stabilizer before the practice of fixing with hypo became standard.
