Potassium monophosphate (aft monopotassium) is a crystalline white powder soluble in water and strong acids are not soluble in ethanol. It is a potassium salt of phosphoric acid. The aqueous solution is hydrolyzed, it has a weak gigroskopichnostyu. Plotnost: 2. 34 g / cm³. Melting point - 252, 6 ° C; boiling temperature - 400 ° C.
Potassium dihydrogen KH2PO4 (potassium dihydrogen phosphate, potassium monophosphate) - potassium salt of phosphoric acid; white powder with a density of 2. 34 g / cm³. Odnozameschёnnye orthophosphates used in the production of phosphate fertilizers in the pharmaceutical industry. Crystals odnozameschёnnyh orthophosphate - valuable ferroelectric and piezoelectric materials. Potassium monophosphate is used as the phosphate and potash fertilizer in solution form for root and foliar application. potassium dihydrogen phosphate used in preparing the buffer.
Chemical formula: KH 2 PO 4 .
The water - soluble orthophosphate, including potassium monophosphate, are prepared by adding the required amounts of orthophosphoric acid H 3 PO 4 to sodium hydroxide or potassium monophosphate karbonatov. Podkormki increase productivity and improve quality of fruits and vegetables due to a better accumulation of sugars and vitamins improve their storability and sugar. When using potassium monophosphate in decorative plant growing faster onset and prolonged blooming flower plants, its use contributes to a better maturation of the shoots and overwintering of ornamental trees and shrubs.
In horticulture greenhouses is a fertilizer used in the preparation of nutrient solutions, especially with irrigation water, characterized by a high concentration of salts, as well as for foliar.
potassium dihydrogen phosphate used in preparing the phosphate buffer is used widely in biochemistry and molecular biology.
Crystals odnozameschёnnyh orthophosphate - valuable ferroelectric and piezoelectric materials, are used as non - linear optical crystals.
