|Product name: ||Sodium Chloride|
|Molecular Weight: ||58.443|
|CAS No.: ||7647-14-5|
Sodium Chloride occurs as a transparent to opaque, white crystalline solid of variable particle size.
Sodium Chloride remains dry in air at a relative humidity below 75%, but becomes deliquescent at higher humidity. One gram is soluble in 2.8 mL of water at 25°, in 2.7 mL of boiling water, and in about 10 mL of glycerin. Sodium Chlo ride containing water-insoluble anticaking, free-flowing, and conditioning agents may produce cloudy solutions or may dissolve incompletely. A 1:20 aqueous solution usually has a pH between 5.5 and 8.5 (the pH may be higher if alkaline conditioning agents have been added).
Sodium Chloride can be used for nutrient, preservative, flavoring agent and intensifier, curing agent and dough conditioner.
