Sodium Chloride
In its edible form of table salt, it is commonly used as a condiment and food preservative. Large quantities of sodium chloride are used in many industrial processes, and it is a major source of sodium and chlorine compounds used as feedstocks for further chemical syntheses
What is Sodium Chloride?
Sodium Chloride is an ionic compound with the chemical formula NaCl.
Sodium Chloride is also known as salt. It occurs in oceans and sea waters. It is also found as rock salt. About 1% to 5 % of seawater is made of NaCl. It is a crystalline solid, white in color. In its aqueous form, it is called a saline solution.
The molecular weight of NaCl is 58.44g/mol
This compound is water-soluble and consists of sodium cation and chloride anion. The sodium and chloride ion are present in the ratio 1:1. It is widely known as table salt and is mostly used in the food industry for preservation and flavoring. The pH of sodium chloride is 7.
