Potassium Hydroxide Solution 0.5 N in Ethanol is a standardized alcoholic solution containing potassium hydroxide (KOH) at a normality of 0.5 N, designed for laboratory analysis, pharmaceutical applications, and calibration purposes.
🏭⚗️ Production
Potassium Hydroxide Solution 0.5 N in Ethanol is prepared by dissolving high-purity potassium hydroxide in ethanol and carefully standardized to achieve a concentration of 0.5 N at 25°C. The solution is stored in tightly sealed containers to prevent moisture absorption and contamination, ensuring long-term stability.
🔬 Properties
The solution is a clear, colorless to slightly yellow liquid, highly soluble in ethanol. It is strongly alkaline and reacts readily with water. The solution remains stable under normal laboratory conditions but should be protected from moisture, air, and extreme temperatures to maintain its concentration and effectiveness.
🧪 Applications
In laboratory settings, Potassium Hydroxide Solution 0.5 N in Ethanol is used for acid-base titrations, saponification reactions, and preparation of ethanolic solutions for analytical procedures. In pharmaceutical applications, it is employed in the preparation of certain drug formulations, pH adjustments in ethanol-based solutions, and stability testing where anhydrous or alcoholic conditions are required.
⚠️ 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 moisture, air, and heat. Disposal should follow laboratory safety protocols and local environmental regulations.
