Chemical Properties:
Sodium chloride (NaCl), also known as common salt or halite, is a white crystalline powder or colorless crystal with a saline taste. Its crystal lattice has a face-centered cubic structure. Although solid sodium chloride is typically anhydrous, it may crystallize as a dihydrate below 0 °C. It is soluble in water, slightly soluble in alcohol, and melts at 804 °C (1480 °F). Sodium chloride is the most important sodium compound and occurs naturally in seawater, underground deposits, and brine wells. It serves as a basic raw material for producing chlorine, sodium hypochlorite, sodium bisulfate, soda ash, and hydrogen chloride. Additionally, it is used in food preparation, fertilizers, and for de-icing roads.
