محلول هیدروکسید سدیم 0.25 نرمال

Sodium Hydroxide 0.25 N is a standardized aqueous solution containing sodium hydroxide (NaOH) at a normality of 0.25 N, designed for laboratory analysis, pharmaceutical applications, and precise titrations.

🏭⚗️ Production
Sodium Hydroxide 0.25 N is prepared by dissolving high-purity solid sodium hydroxide pellets in distilled or deionized water and carefully standardized to achieve a normality of 0.25 N at 25°C. The solution is stored in tightly sealed containers to prevent absorption of carbon dioxide from the air and maintain long-term stability.

🔬 Properties
The solution is a clear, colorless liquid that is highly soluble in water. It is strongly alkaline and reactive, remaining stable under normal laboratory conditions if protected from carbon dioxide, moisture, and contaminants.

🧪 Applications
In laboratory settings, Sodium Hydroxide 0.25 N is used for acid-base titrations, pH adjustments, and analytical procedures requiring a controlled alkaline environment. In pharmaceutical applications, it is employed for preparation of buffers, formulation adjustments, and quality control assays to ensure product stability and efficacy.

⚠️ Safety
The solution is corrosive and must be handled with care. Contact with skin or eyes should be rinsed immediately with plenty of water, and gloves, goggles, and lab coats should be worn during handling. The solution should be stored in tightly sealed containers in a cool, dry place, away from carbon dioxide, air, and heat. Disposal should follow laboratory safety protocols and local environmental regulations.
