Potassium Dihydrogen Phosphate

Potassium dihydrogen phosphate (chemical formula: KH2PO4) is stored in a sealed container and is stable in air. It loses water at 400 ℃ and becomes pyrophosphate. It is used to prepare buffer solutions, determine arsenic, antimony, phosphorus, aluminum, and iron, prepare phosphorus standard solutions, prepare culture media, and measure inorganic phosphorus and alkaline phosphatase activity in serum

Products Details

Colorless tetragonal crystal or white crystalline powder. The relative density is 2.338. Melting point 252.6 ℃. Dissolved in water (83.5g/100ml at 90 ℃), the aqueous solution is acidic, and the pH value of a 1% potassium dihydrogen phosphate solution is 4.6. Insoluble in alcohol. Has deliquescence. When heated to 400 ℃, it melts into a transparent liquid and solidifies into an opaque glassy potassium metaphosphate after cooling
