FAQ

What is Sodium chloride (CAS: 7647-14-5)?

Sodium chloride, with CAS number 7647-14-5, is a chemical compound composed of sodium and chlorine ions (NaCl). It is a white, crystalline solid commonly known as table salt. Highly soluble in water, it dissociates into Na⁺ and Cl⁻ ions, making it an essential electrolyte. Sodium chloride occurs naturally in seawater and rock salt deposits. Its ionic structure and solubility make it vital in biological systems and industrial applications.

What are the main uses of Sodium chloride (CAS: 7647-14-5)?

Sodium chloride (CAS 7647-14-5) is widely used in pharmaceuticals for saline solutions, in food as a seasoning and preservative, and in industry for de-icing roads, water treatment, and manufacturing processes. It also serves as a reference material in research and is used in chemical synthesis. Its versatility stems from its solubility, conductivity, and role in maintaining fluid balance in living organisms.

Is Sodium chloride (CAS: 7647-14-5) safe?

Sodium chloride (CAS 7647-14-5) is generally safe in normal use. It is non-toxic and approved for food and pharmaceutical applications. However, inhalation of dust or contact with eyes may cause irritation. Safety standards like OSHA and WHO regulate its handling. Ingestion of large amounts can lead to toxicity, so proper storage and usage are essential to ensure safety.

How should Sodium chloride (CAS: 7647-14-5) be stored?

Sodium chloride (CAS 7647-14-5) should be stored in a cool, dry place away from moisture. Keep in airtight containers to prevent clumping and contamination. Avoid exposure to light, as it may degrade the compound over time. It is stable under normal conditions but should be handled to maintain purity. Proper storage ensures longevity and safety in all applications.
