25 KG/Bag White Crystal Powder Mono Potassium Phosphate Cas 7778-77-0 Used For Fertilizer
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 metaphosphate.
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.
analysis reagent, pH buffer. For the preparation of buffer, determination of arsenic, antimony, phosphorus, aluminum and iron I preparation of phosphorus standard solution and haploid breeding medium, determination of serum inorganic phosphorus, alkaline acid enzyme activity, preparation of bacterial serum test Leptospira medium and the like. It is also used for the generation of harmonics of piezoelectric elements, electro-optical elements and laser light.phosphoric acid was added to water.
phosphoric acid was added to water, and potassium hydroxid
