سدیم هیدروکساید سولوشن 32%

Sodium Hydroxide Solution 32% is a concentrated alkaline aqueous solution widely used in pharmaceutical manufacturing and laboratory processes for its strong pH‑regulating, neutralising, and cleaning capabilities.

🏭⚗️ Production
Sodium Hydroxide (NaOH) is industrially produced via the chlor‑alkali process (electrolysis of sodium chloride brine), which also generates chlorine and hydrogen as by-products. The 32% aqueous solution is then prepared by carefully diluting concentrated NaOH with purified water under controlled conditions, producing a high-purity, stable alkaline solution suitable for pharmaceutical and laboratory applications.

🔬 Properties
Sodium Hydroxide Solution 32% exhibits very high alkalinity. It is completely miscible with water, generates heat upon dilution, and reacts vigorously with acids to form salts and water. The solution is chemically stable under sealed, corrosion-resistant storage when protected from carbon dioxide, which can slowly convert NaOH into sodium carbonate.

🧪 Applications
In pharmaceutical formulations, Sodium Hydroxide Solution 32% is used as a pH-adjusting agent, neutralizing agent, and process reagent during synthesis, purification, and formulation steps. It is particularly important in preparations requiring precise pH control, such as ophthalmic solutions, sterile injectables, and multi-dose containers.
In laboratory settings, the solution serves as a standard titrant, cleaning agent for glassware and reactor vessels, and neutralizer of acidic reagents or residues. It is widely used in analytical chemistry, microbiological sample preparation, and other experiments that require strong alkaline conditions.

⚠️ Safety
Sodium Hydroxide Solution 32% is highly corrosive and can cause severe chemical burns upon contact with skin, eyes, or mucous membranes. It generates heat during dilution and must be handled with appropriate protective equipment, including gloves, goggles, and lab coats. The solution should be stored in tightly sealed, corrosion-resistant containers, away from acids, oxidizing agents, and moisture. In pharmaceutical or laboratory environments, proper spill response and neutralization procedures must be in place.
