White Crystal 25 KG/BAG Mono Potassium Phosphate For Fertilizier
Mono Potassium Phosphate'S PH is 4.4 ~ 4.7. Stable in the air. It is hygroscopic, easily soluble in water, insoluble in alcohol, slightly alkaline in aqueous solution, dehydration of molecular content when 204, and PH value of 1% aqueous solution is 8.9. Solubility in water: 222g/L (20°C).
Colorless columnar crystal or white crystalline powder. Melting point 96 C; d 2.34. Stable in air. Soluble in about 4.5 water, the aqueous solution is acidic, pH 4. 4~4.7. Insoluble in ethanol. At 400 deg C water loss to form potassium metaphosph
Phosphoric acid was added to water, and potassium hydroxide or potassium carbonate was added thereto. The filtrate was concentrated to a relative density of 1.32 by heating and filtration. Cooling, suction and filtration out of the crystal, that is, potassium dihydrogen phosphate.pf.
