Sodium+Chloride

Properties:
Sodium chloride is readily soluble in water because of its ionic bond structure. It is insoluble or only slightly soluble in most other liquids. It forms small, transparent, colorless to white cubic crystals. Sodium chloride is odorless but has a characteristic taste. It is an ionic compound, being made up of equal numbers of positively charged sodium and negatively charged chloride ions.

Basic Facts:
__**Formula**__: NaCl Sodium Chloride is table salt, also known as common salt. It is a food preserver, and commonly used as a condiment.

Uses:
Sodium Chloride is also used to produce sodium carbonate and calcium chloride. Sodium carbonate is then used to produce glass, sodium bicarbonate, and certain dyes. As we can see, Sodium Chloride is used to make many different products. It is also has many different uses in the many different fields. It is used in softening hard water, salting of the roads during icy conditions, the industrial industry with curing of the concrete in the cement castings, also it has a large part in processing aluminum, beryllium, copper, steel, and vanadium. One other industry is the pulp and paper and the sodium chloride is used to bleach the wood pulp. Something that is an everyday product that is mandatory in everybody's house is a fire extinguisher. Fire extinguishers contain sodium chloride and that is the principal extinguishing agent.

When salt is added to water: NaCl = Na + + Cl -



Environmental effect
Road salt ends up in fresh water bodies and could harm aquatic plants and animals by disrupting their osmoregulation ability. The omnipresence of salt poses a problem in any coastal coating application, as trapped salts cause great problems in adhesion. Naval authorities and ship builders monitor the salt concentrations on surfaces during construction. Maximum salt concentrations on surfaces are dependent on the authority and application. The IMO regulation is mostly used and sets salt levels to a maximum of 50 mg/m2 soluble salts measured as sodium chloride. These measurements are done by means of a Bresle test. In highway deicing, salt has been associated with corrosion of bridge decks, motor vehicles, reinforcement bar and wire, and unprotected steel structures used in road construction. Surface runoff, vehicle spraying, and windblown actions also affect soil, roadside vegetation, and local surface water and groundwater supplies. Although evidence of environmental loading of salt has been found during peak usage, the spring rains and thaws usually dilute the concentrations of sodium in the area where salt was applied.
