Iron Phosphate | Formula, Properties & Application
Iron Phosphate, represented by the chemical formula FePO 4, has molar mass of 150.82 g/mol. It is a grayish white or yellowish powder that is insoluble in water but soluble in strong acids. It exhibits paramagnetic behavior, meaning it is only magnetized in the presence of an external magnetic field, and is demagnetized when the field is removed.
