Sodium chloride  commonly known as edible salt, is an ionic compound with the chemical formula NaCl, representing a 1:1 ratio of sodium and chloride ions. It is transparent or translucent, brittle, hygroscopic, and occurs as the mineral halite. In its edible form, 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. Another major application of sodium chloride is de-icing of roadways in sub-freezing weather.Sodium Chloride 99.5% AR is a high-purity grade of common salt, meaning it has a minimum purity of 99.5% and is suitable for use as an Analytical Reagent. This grade is specifically purified and tested to meet stringent quality standards, making it ideal for laboratory analysis, research, and pharmaceutical applications where high purity and low impurity levels are crucial.
