پتاسیم دی هیدروژن فسفات

Potassium dihydrogen phosphate is a colorless or white crystalline inorganic salt widely used as a fertilizer, buffering agent, and in food additives. It is valued for its high solubility and ability to provide both potassium and phosphorus nutrients.

🏭⚗️ Production
It is commonly produced by reacting phosphoric acid with potassium hydroxide or potassium carbonate, followed by crystallization. Industrial production involves precise control of pH and temperature to obtain pure, well-defined crystals, often used in agricultural and food industries.

🔬 Properties
The chemical formula is KH₂PO₄ with a molar mass of approximately 136.09 g/mol. It appears as odorless, white crystalline powder or granules, highly soluble in water, and forms acidic to neutral solutions depending on concentration. It is stable under normal conditions but can decompose at high temperatures, releasing phosphates and potassium oxides.

🧪 Applications
Potassium dihydrogen phosphate is widely used as a fertilizer to supply essential potassium and phosphorus for plant growth. It serves as a buffering agent in food and pharmaceutical formulations, maintaining pH stability. Additionally, it is used in laboratory buffer solutions and in electrolyte preparations for cell culture and other biological applications.

⚠️ Safety
Generally regarded as safe, but contact with large quantities may cause mild irritation to skin and eyes. Inhalation of dust should be avoided to prevent respiratory discomfort. Proper handling includes using gloves, masks, and goggles in dusty environments, and storing the compound in a cool, dry place away from incompatible materials like strong bases.
