محلول هیدروکسید پتاسیم 0.1 نرمال در اتانول

Potassium Hydroxide (KOH) Solution 0.1 N in Ethanol is a standardized alcoholic solution used in pharmaceutical and analytical laboratories for acid–base titrations, saponification tests, and ester analysis. Dissolving KOH in ethanol provides a non-aqueous medium suitable for reactions where water-sensitive compounds are involved.

🏭⚗️ Production
Prepared by accurately dissolving high-purity potassium hydroxide pellets in absolute ethanol under controlled conditions, followed by dilution to the desired normality (0.1 N). The solution is stored in tightly sealed, chemically resistant bottles to avoid absorption of moisture and carbonation from air. Standardization is performed using a primary standard acid such as benzoic acid or oxalic acid in non-aqueous titration.

🔬 Properties
A clear, colorless liquid, strongly alkaline and highly soluble in ethanol. It is non-aqueous, hygroscopic, and reacts vigorously with water or acids. The solution is flammable due to its ethanol content and should be handled carefully.

🧪 Applications
Used in non-aqueous titrations to determine the acidity of pharmaceutical compounds, fatty acids, esters, and other water-sensitive substances. It is commonly employed in quality control, saponification number determinations, and analytical assays where precise base concentration is required.

⚠️ Safety
Corrosive and flammable. Can cause severe burns and eye damage. Handle with gloves, goggles, and lab coat in a well-ventilated area or fume hood. Keep away from heat, sparks, and open flames. Store in a tightly closed, cool, and dry container. Spills should be neutralized carefully, and disposal must follow laboratory and environmental regulations.
