Feed MKP/Monopotassium Phosphate
Chemical formula: KH2PO4
Molecular weight: 136.09
Properties: Colorless cubic crystal or white crystal powder. Relative density is 2.338, and melting point is 252.6 centigrade. It is soluble in water and insoluble in ethanol, and the aqueous solution shows acidity. It melts and becomes transparent liquid at 400 centigrade. After refrigerating, it becomes opaque potassium metaphosphate. It is easy to deliquesce.
