Sodium Chloride NaCl CAS 7647-14-5

Common Chemical Reactions

Electrolysis (Chlor-Alkali Process): When an aqueous solution of Sodium Chloride is electrolyzed, it produces chlorine gas (Cl₂), hydrogen gas (H₂), and sodium hydroxide (NaOH), which are foundational chemicals for global industry.

Precipitation: Reacts readily with silver nitrate (AgNO₃) in solution to form a dense, white silver chloride (AgCl) precipitate, a standard reaction used in analytical chemistry.

Specifications

Applications & Key Roles

• Chemical Manufacturing: Serves as the primary raw material in the chlor-alkali industry for synthesizing chlorine, soda ash, and caustic soda.
• Water Treatment: Acts as the regenerative agent in water softening systems, replacing calcium and magnesium ions in hard water with sodium ions.
• De-icing and Winter Maintenance: Lowers the freezing point of water to effectively melt ice and snow on roadways and commercial pathways.
• Food and Beverage: Functions as a critical preservative and flavor enhancer, controlling microbial growth through osmotic pressure.

Storage Environment Requirements

• Store in a cool, dry, and well-ventilated warehouse.
• Keep containers tightly closed to prevent moisture absorption, as the product is hygroscopic.
• Isolate from strong acids and strong oxidizing agents to maintain chemical integrity.
• Ensure pallets are kept off the ground to avoid dampness from concrete floors.

Handling & Usage Precautions

• Minimize dust generation and accumulation during transfer and processing.
• Ensure adequate exhaust ventilation in enclosed work areas.
• Wear appropriate personal protective equipment (PPE), including safety goggles and dust masks, to prevent eye and respiratory irritation.
• Wash hands and exposed skin thoroughly after handling.

Common Formulations & Functions

• Isotonic Saline Solution (0.9% NaCl): Formulated with pure water, it matches the osmotic pressure of human blood and is used globally in medical, laboratory, and cosmetic applications as a safe diluent or flush.
• Brine Solutions (High Concentration NaCl): Used in industrial refrigeration and food preservation. The high salt concentration creates a hypertonic environment that effectively prevents bacterial multiplication.
• Ion-Exchange Brine: Formulated for water softeners, the solution acts as a rapid delivery system for sodium ions to recharge resin beads efficiently.

Packaging

• Fiber drum or carton box, lined with PE bag.
• Customized packaging available upon request.
