دی پتاسیم اگزالات مونوهیدراته

Di-Potassium Oxalate Monohydrate is a high-purity inorganic salt widely used in analytical, electrochemical, pharmaceutical, and laboratory applications. As a stable oxalate source with controlled hydration, it is valued for its buffering capacity, complexing ability with metal ions, and consistent analytical performance in titrimetric and standardization procedures.

🏭⚗️ Production
Produced by neutralization of oxalic acid with potassium carbonate or potassium hydroxide under controlled conditions, followed by crystallization from aqueous solution. The monohydrate form is obtained through regulated drying and crystallization processes to ensure precise water content. High-purity grades undergo recrystallization and filtration to remove insoluble residues and trace metal contaminants. Quality control testing includes assay (titrimetric), identification, loss on drying (water content), pH (5% solution), heavy metals, chloride, sulfate, and insoluble matter. Material is supplied in moisture-protected containers to preserve hydration state and prevent caking.

🔬 Properties
White crystalline powder or colorless crystals with odorless appearance. Freely soluble in water and practically insoluble in alcohol. Aqueous solutions are mildly alkaline. Forms stable complexes with calcium, iron, and other multivalent metal ions. Upon heating, decomposes to potassium carbonate with release of carbon monoxide and carbon dioxide. Stable under normal storage conditions but hygroscopic in high humidity environments.

🧪 Applications
Widely used as a primary or secondary standard in redox titrations, particularly for standardization of potassium permanganate solutions. Applied in electroplating baths, photographic processing, and metal surface treatment. Functions as a complexing and chelating agent in analytical chemistry. Utilized in pharmaceutical formulations and laboratory buffer systems where controlled oxalate concentration is required. Also employed in research involving metal-ion coordination chemistry.

⚠️ Safety
For laboratory and industrial use. Harmful if swallowed in large quantities. May cause irritation to eyes, skin, and respiratory tract. Oxalates can bind calcium ions and may pose health risks if ingested. Avoid inhalation of dust and contact with eyes or skin. Handle with appropriate personal protective equipment including gloves, lab coat, and safety goggles. Store in a cool, dry, well-ventilated area away from strong oxidizing agents and acids. Dispose of according to local environmental and chemical waste regulations.
