Molecular formula : CAS :
nature : multivariate acid or high metal ions generated by stepwise saline solution often called hydrolysis gradually. If the hydrolysis PO43- on three stages, gradually generating HPO42-, H2PO4- , H3PO4 and OH-. Again [Fe (H2O) 6] 3 + Hydrolysis is gradually generating [Fe (H2O) k5OH] 2 + and [Fe (H2O) 4 (OH) 2] +, Fe (OH) 3 and H3O +. Usually the first-class hydrolysis than the inclination to follow-up class.
