What concentration of fe needed to maintain phosphate

Reference no: EM13316915

FeCl3 is added to remove excess phosphate. The following reactions occur (the charges are in parentheses): FeCl3 -> Fe(3+) + 3Cl(-) Fe(3+) + PO4(3-) -> FePO4 The equilibrium constant for the second reaction is 10^26.4. Ksp = 10^-26.4 for the reverse reaction. what concentration of Fe(3+) is needed to maintain the phosphate concentration below the limit of 1 mg P/L?
