Potassium Permanganate Solution 0.1 N is a standardized aqueous solution of potassium permanganate with a normality of 0.1 N, intended for redox titrations, analytical determinations, and laboratory use requiring precise oxidizing strength.
🏭⚗️ Production
Potassium Permanganate 0.1 N solution is prepared by dissolving accurately weighed high-purity potassium permanganate crystals in distilled water. The solution is allowed to stand to remove any insoluble impurities and then standardized against a primary standard before packaging in dark, airtight containers to prevent photodecomposition and maintain chemical stability.
🔬 Properties
Potassium Permanganate (KMnO₄) is a dark purple crystalline solid, and its 0.1 N aqueous solution appears deep purple. The solution is a strong oxidizing agent, highly soluble in water, and exhibits a characteristic violet color. It has a pH of approximately 7 in neutral solution and decomposes on exposure to light or heat, producing manganese dioxide and oxygen.
🧪 Applications
Potassium Permanganate 0.1 N is used as a primary oxidizing agent in redox titrations, water analysis, and pharmaceutical quality control. It is employed in the determination of iron, oxalate, and other reducing agents, as well as in disinfection and analytical method development requiring a standardized oxidizing solution.
⚠️ Safety
Potassium Permanganate solution is a strong oxidizer and can cause burns to skin and eyes. It is harmful if ingested or inhaled and may stain skin and clothing. Handle in a well-ventilated area while wearing gloves, goggles, and protective clothing. Store in tightly-sealed, dark containers away from organic materials and reducing agents, and dispose of waste according to laboratory safety protocols.
